Recording "done button" action in "User Notes"

When a student ends an exam by pressing the "done button", that action is recorded as a user note which can be viewed by course personnel on the student's personal information page.

- Slots can now require each student to check-in from a unique IP address
  when using a particular slot for a specific resource. The IP address of
  the student's computer is then tied to that student's access to the resource
  thereafter, until the end date of the slot.
  (Intended use case is high stakes online testing where students are using
  computers with statically assigned IP addresses).

  All existing calls to create_submenu have been adjusted.
- moved special treatment of the Personal menu from create_submenu to primary_menu
- added help icon to Help submenu in XML editor.

- Bug 6518.
  - Speed-up display of Course Contents where content blocking is in

added dropdown menu to insert problem templates into xml editor (thanks to tobias reinhardt)
added feature of saving current scrollposition on save when editing problems
added possibility to fold blocks in colorful editor, this state will be saved and restored
added shortcuts to create empty problems, html files and directories

and other smaller features and bugfixes

- Coding style: sort() keys()

coding style

- Modification to rev. 1.341.
  - Style: grep(), standard indent.
  - Tighten up regexp.

Improve internationalization:
- Proper compilation of output string, then pass to translation
- Re-use existing phrases

Internationalization: Do not translate help filename (corrects rev. 1.292)

Bug #6689: Do not provide example link for templates which contain nothing to display.

Correction to rev. 1.339: actually no double translation now

Correct and improve error message:
- Internationalization: Do not translate already translated phrase.
- Style/Output: Error style not needed here - message will be wrapped in error style in sub routine

- Replace term: "Construction Space" with "Authoring Space" for
  consistency with type of role used to access it, and action taken there.

- Bug 5453.
  - Assistant co-authors can browse published resources from the authoring
    space for which they have the aa role.

- Sanity checking.

Bug 6455 - Progress Indicator now jQuery. Still need to test across browsers.

- &check_slot_access() can return additional statuses: RESERVABLE, RESERVABLE_LATER.
  NOTRESERVABLE.

- Bug 2802.
  - Separate decision on leniency in grading from logic on whether additional
    new submission is possible for partially correct problem parts.
  - new parameter: retrypartial set to "yes" if part is to be answerable
    when partially correct.
  - custompartial.problem template incorporates retrypartial parameter in
    place of lenient parameter.
  - points awarded > 1 no longer considered 'partially correct'.
  - &grading_is_nonlenient() moved from inputtags.pm back to optionresponse.pm

"Harmless" first usage of modal windows: examples for problem templates

- Bug 2802.
  - optionresponse::is_nonlenient() moved to inputtags::grading_is_nonlenient()
    to facilitate re-use.
  - where solved is "correct", awarded value < 1 permits new submission,
    only if lenient grading applies.
  - add lenient parameter to custompartial.problem template.

- &authorspace() routine now takes an argument: $uri
  so "Construction Space" breadcrumb points at appropriate author space
  for resource/directory being viewed or acted om.
  - current role could be different or ("no role" - i.e., cm), so is only
    used to determine authorspace when $uri is unavailable.

- Bug 1320.
- Use lonDocRoot perlvar in place of static string: '/home/httpd/html'.

In process of removing remote control, remote navmap and different icon modes code
Also some minor refactoring.

- Removed now unused style "LC_edit_problem_divide"

Added some breadcrumbs to Construction Space

To get rid of the title_bar, customized titles aren't allowed anymore.

Moved special title for Construction Space pages from &start_page() to new routine &CSTR_pageheader(). Since &start_page() isn't the only routine called to create the page header, the centralized creation of the CSTR page header code can't be currently called in &start_page(). This needs to be done at each place where &start_page() is called.

First changes to get rid of customized page titles:
- Moved CSTR page header code from start_page to new sub routine &CSTR_pageheader()
- Currently keep old header but use &CSTR_pageheader()
- Directly call &CSTR_pageheader() in CSTR related scripts (lonpubdir.pm, lonhomework.pm, structuretags.pm)
  (More scripts need to call this routine)
- Added new sub routine &head_subbox() to create head_subbox which contains page related links and functions, etc.
- Added styles for &head_subbox()
  (Currently implemented as LC_head_subbox2 to avoid conflicts with code created by lonhtmlcommon::breadcrumbs - will be changed)

Other but related changes:
- Added some breadcrumbs to CSTR
  (Only basic calls - links and structure has to be added/revisited)
- Adjusted styles used for breadcrumbs:
    - Replaced hardcoded border color by dynamical standard border color
    - Removed margin to allow direct concatination with head_subbox

- Added some FIXME comments to mark work in progress

XHTML: Attributes in lower-case only (<form method="post" ...)

- Make return from &check_slot_access() consistent with information available in Navigate Contents and Manage Reservations, for .problem which uses slots, for which previously checked-in slot has closed, but problem remains answerable (should a new slot become available).

Optimizations and standardization for "Calculate answers" screen
- Replaced special table by standard data_table
- Optimized &mt usage
- Make the headline a headline
- Removed calls of non existing styles "thinborder" and "center"
- Shortened code lines by inserting line breaks

- Optimized &mt usage and updated related phrases in de.pm and zh.pm
- zh.pm changes include hash key changes from de.pm 1.261

- Backport part of 1.301, 1.303, 1.304, 1.305, 1.306.

XHTML conform javascript start tag attributes

Localization:
Optimized &mt() usage for error message and standard style for filename
(re-use existing translation phrase)

Removed unused variable to build Cheatsheet table
(This is done further done and existed already)

- Bug 5870. (\Q escape used by default in regexp in lonnet::delenv()).

Removed extra line at 907 which was accidently put in by JMS on 2.13.2009

"Script Functions" help item has been added to EditXML screen

POD documentation changes

Converted/added POD comments

SUpport parameterizing the math popup so different applets can be
selected in different contexts.`

Bug 5777
- IP-based access control extending to encompass additional resources (i.e., HTML files, Bulletin Boards, External Resources, Simpe Pages), beyond existing support for problem/exam/survey files.
- New lonipcheck.pm added as a chained content handler, called after londatecheck.
- &check_ip_acc() moved form lonhomework.pm to loncommon.pm to be more widely available.

- Separate code used to create button and code used to generate javascript
  fired by button click.
- Rename routines as &dragmath_button() and &dragmath_js().
- Only include javascript used to launch DragMath pop-up once in Colorful editor screen.
- Do not include Edit Math button when WYSIWYG is on ("Render Latex" button in pop-up was not writing to textarea in this case) - need to integrate Drag Math into FCKedit for this situation.
- Add contextual help for Edit Math button
- Move "Edit Math" button in "EditXML" mode.

Factor out generation of dragmath -> text area, so that this can
be re-used in the multicolored monster/editor.

bz 5744 - Add "Edit Math" button to bring up dragmath to edit equations and
insert the text into a resource being edited in xml editor.

More help links, better labels, better column distribution for templates.

Bug #1724: Categories, helplinks, and examples for templates

Change arguments accepted by lonnet::appenv() to:
1. reference to hash
2. (optional) reference to array.

Change all instances where lonnet::appenv() is called to replace first argument passed (originally a hash) to a reference to the hash.

- Modify lonnet.pm rev 1.35 code intended to prevent "dangerous" modifications of the environment, so it will actually do this.
- Allow these modifications to be made in certain instances:
   DC switching to adhoc role
   CC switching to a different course role in the current course.
   user self-enrolling as a student

Ever since we have the Undo-button, the user really does not need this info anymore.

Bug 5579. Form elements named problemmode were moved in structuretags.pm rev 1.408.  The result was that a button click of 'Calculate Answers' resulted in @{$env{'form.problemmode'}} in which the last array item was 'View' not 'Calculate Answers'.

Eliminate the dependency on form element ordering by setting the value of problemmode on a buttonclick via javascript:setmode().

When using calls to &Apache::lonnet::EXT(), request a scalar explicitly, to avoid similar problems to those eencountered in bug 5578, following the change in lonnet.pm rev 1.927 which enabled EXT() to return the level a parameter is set at, if an array was requested.
