   - Prompt to confirm overwrite now supported for resources in .page.
   - &file_delchk_js() and &file_overwritechk_js() routines in structuretags.pm

     to facilitate re-use.
   - Calls to &file_overwritechk_js() omitted from individual resources if
     enclosing map is .page.  Single call from lonpage.pm instead (with
     refs to hashes with information about paths and numbers of response items
     in resources in .page included there.
   - Pop-up confirmations for overwrite and/or deletions supported for both
     "Submit Answer" and "Submit All" button presses.
   - Triggers for multiple response items aggregated into one pop-up

Fix cycle of "Edit Resource" and going back

Faculty training: somehow people did not find the beautiful icons

Move "return" button to where the other navigation arrows are (also, it's
not a function that is available in courses at all times, so it should
not have been in the line where it was)

For 3.0: directly jump into relevant parameter screen. Testing with "maxtries"

Simplified status bar counter step default (rev. 1.275, 1.277): just > 0 is enough

Optimized status bar localization:
Overhauled status text creation to allow proper translation.
    - Translate whole sentence instead of unhandy phrase fragments concatenation.
    - Simplified way of time text creation by using quant.
    - Removed code for not anymore supported old browsers (bug 1382).
    - Indirectly corrects mt() call with incorrect parameter (_2 -> _1)

- Allow values 0 < x < 1

Update documentation for changes made in 1.275

Status Bar:
Introduce optional parameter for lonhtmlcommon::Increment_PrgWin() to allow other counter steps than 1 (solves side effects of bug 6022 resolution).
Default is 1.

The last breadcrumb of course breadcrumbs is supposed to be wrapped in <b> tag, not <h1>.

Bugzilla #6246

Bugzilla #6266
tested in:
    - IE8/Win, Saf4.0.5/Mac, FF3.6.3/Mac
    - IE6/Win: requires explicit set properties (inheriting does not work!)

More breadcrumbs, remove unneeded code.

Saving my work ...

- Backport 1.266, 1.269.

- First breadcrumb item is a course or a menu link.
  - default to menu link if course has no description.

Corrected r1.267.

Removes "Disable WYSIWYG Editor" and removes the commented-out line to "Enable WYSIWG Editor" since this preference is no longer respected on a global basis.  This should also be removed from the Main Menu...

Localization: Corrected &mt() call

Work-in-progress commit on bug 6209.

--> New (still non-functional) contextual section bar and section title bar
--> Disable "Enable/Disable WYSIWYG" link
--> Hide unnecessary fields in .LC_Box'es temporarily for display purposes
--> No longer preview content above edit box
    --> This will eventually be replaced by a "Preview" button which
        will generate a processed copy of the field via an AJAX request.
--> No longer print "Save all", "Delete", etc. fields beneath edit box,
    because I am masochistic and wanted to get rid of the only part
    of the interface that actually works as advertised right now.

STILL NOT TOUCHED:
-- same as last commit

New pretty screenshot attached on Bugzilla.

- Backport 1.262, 1.264, 1.265.

Error-messages in a confirm-success-box now have the same font-size as the success-messages. Partly there are both kinds of messages in one box, so it looks better if they have the same font-size.

Regexp inside raw_href_to_link() now stops match upon finding "<" in order
to prevent "http://mysite.com<br/>" from turning the "<br/>" into
part of the link.

bug 6195 -- URLs included in templated pages are broken

Bug 6184
    Disable WYSIWYG in Construction Space

-- Removes the old FCKEditor initialization JavaScript, so
   only the new CKEditor instances, which are explicity
   created, will generate rich text editors

-- Removes <script> for FCKEditor, which should save some
   bandwidth as it is no longer required.

Comment:  Just in case, I am leaving the actual FCKEditor source
          in CVS for the near future.

- xhtml.

- Fix bug 5795.

- Bug #6064 Breadcrumbs will be visually cut off if text is too long to fit into one line.
- Bug #6081 Breadcrumbs that don't have an href attribute are no longer wrapped with <a> tag.
- Added some POD in lonhtmlcommon and repaired errors and warnings reported by podchecker.
- new functions in lonhtmlcommon:
  o list_from_array: constructs a XHTML list from arraydata
  o funclist_from_array: constructs a XHTML list from arraydata with first item highlighted (see other funclist functions)

Bug 6179
    Rich Text Editor should not respect old WYSIWYG preference

Adding CSS link tag for jQuery UI

bug 6173: Rich Text Editing not enabled in IE

recommit of changes by bisitz in r1.254 that were accidentally reverted

-- Adds hackish method to revert back to previous behavior (global preference)
   if none of the new HTML classes are present.  This way, all textareas
   must explicitly be changed for now, and behavior is backwards-compatible.

-- Adds jQuery script tags to HTML output
-- Adds CKEditor script tag where FCKEditor is enabled, while the two editors persist
-- Adds JavaScript functions to detect block-level HTML in a text-area,
   create and destroy rich text editors on demand using jQuery.
-- Adds JavaScript event handler using jQuery to toggle text and CSS classes,
   and create/destroy editors.
-- Adds window.onload code to generate CKEditor instances where desired
   using HTML classes "LC_richAlwaysOn", "LC_richDetectHTML", "LC_richDefaultOn"
   and "LC_richDefaultOff"
-- When editors are not generated but are allowed, links saying "Rich Formatting >>"
   are dynamically inserted, and if editor is generated, link saying "<< Plain text"
   is provided to disable editor if allowed

- Corrected date setting logic:
  Empty date/time fields are not initialized anymore with current time, if empty fields are explicitly requested.
  This fixes bug 5795.
- Overhauled code: simplified code structure
- Added comments to code

Customization for GCI_3.
  - early out if menulink is '_nomenu' and there are no other breadcrumbs.
VS: ----------------------------------------------------------------------

- Customization for GCI_3
  - Ability to suppress initial "Menu" item in breadcrumbs.
  - Do not use course title as text for first item in breadcrumbs.

Bug #2069 - do not turn hard-coded <a>-links into link-links (and thus make a mess)

Font size standardisation for filenames, links, crumbs / Bug 6114:
- lonhtmlcommon::crumbs:
    - Eliminated size (font resize) parameter: Always generate code which uses standard font size. Removed deprecated font size tag.
    - Eliminated noformat parameter: The routine should generate content, not special styles or formats. If a different style/format is really needed, it can be added from outside. Due to consistency, currently no special styles/formats are used, only LC_filename. loncommon:CSTR_pageheader needs to be revisited anyway.
    - Use LC_filename for path and filename
    - Only single space before target attribute
    - Standard code indention
- Decrease default font size for LC_filename
- No different font size for links (<a>)
- CSTR Header: only display lastitem when not empty
- Optimized line breaks on browse resource / import resource screen

- Only include path in recently visted list in RES, if user currently
  has bre or bro priv for the path.

Fix: tags closed in wrong order. this caused parsing problems in some browsers.

- Backport 1.241, 1.249.

- Typo.

Changed topic_bar(). The number is not represented by an image anymore. So you are now able to call topic_bar() with a number greater than 9 or even with a letter.

Link to Course Preferences

Corrections:
- end_funclist: Additional change to lonhtmlcommon.pm 1.244 needed: fieldset not used anymore
- dragmath button: XHTML conform HTML attribute list (comma not allowed)

Fixed an issue that caused tools to appear multiple times in construction space.

Changed layout of head_subbox, which now uses less space.
Removed vertical-align from LC_noBorder, which isn't supposed to define alignment.
The class of icons in head_subbox is now LC_icon which covers the intended alignment change.

-lonhtmlcommon:
    Added a new argument for function row_title. Now you can pass through this argument more attribute for the <tr> Tag
-lonparmset:
    Changes in Table Mode:
    Delete the space between pickbox "Select Parameter Level" and pickbox "Select Enclosing Map or Folder". If you choose as Parameter Level
    >>Course Level<< you will hide the row that enclosed the pickbox "Select Enclosing Map or Folder".

Changed innerregister menu to a new layout. All options available to students are
listed in the same line as breadcrumbs, advanced options which are only available
to roles such as course coordinators are listed in a seperate menu below.
This is work in progress.

- Bug 4315.
