using a div and CSS instead of br to better control spaces around foils, especially when a div or p is used before the response

authoring space overhaul
this update tries to improve the user experience of the authoring space.

added codemirror for xml editor and script tags in colorful editor
added possibility to deactivate codemirror in author settings
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

More practicable and consistent output of previous tries with incomplete answers:
Explicit display of empty answer items, i.e. not submitted

Bug #6694 - Proper display of student's submission on previous tries screen for matchresponse, optionresponse, rankresponse

- Can view own submissions in anonymous surveys.

Improved spacing in colorful editor:
- More and consistent spacing between options
- Minimize missunderstanding to which element a help icon belongs to
- Less needed total window width in editor

- Bug 6595.
  - Derived from code suggested by Christian Knieling (KIT).
  - Additional attribute: "columns", works in tandem with existing attribute:
    "direction". If columns not set, defaults to number of items (i.e.,
    generates a single row, for direction=horizontal, or 1 - single column -
    otherwise).
  - If set to an integer (e.g., 3) will label items as:
    A B C
    D E F
    for direction=horizontal

    or

    A C E
    B D F
    for direction=vertical

- 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

- 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.

- Backport 1.84.

- Check if items are refs for hashes and arrays.
- Use of defined on aggregates (hashes and arrays) is deprecated.

- Bug 2802.
  Move determination of lenient vs non-lenient to subroutine to facilitate reuse
.
  - Support lenient parameter for matchresponse as well as optionresponse.
  - Use response::get_param_response() to retrieve lenient parm.

- Additional (eighteenth field) BubblesPerRow in Bubblesheet Format file.
  - specify bubbles available for each question row (default is 10).
- Support case where question (or subquestion for optionresponse,
    matchresponse, or rankresponse) requires more bubbles than in one line.
  - Students prompted to bubble once in multiple lines.
  - Numbering recognizes multiple lines per question.
  - Also supports: imageresponse, stringresponse, formularesponse where
    students leave link(s) blank if weight assigned is greater than
    bubbles per line -- multiple lines also supported in this case.

For example:
- 15-bubble MSU Art History exams now supported on standard 10-bubble
    bubblesheets used at MSU.

- New Question Type - randomizetry
  - Only set dropdown lists to selections last try when displaying options
    for new try, if rndseed for last try is the same as for current try.

Removes PDF-forms fracments in printouts from problems in exam-mode.

- New awards for surveys:
 ANONYMOUS ANONYMOUS_CREDIT SUBMITTED_CREDIT
  - given for question types: anonsurvey, anonsurvey_cred, survey_cred.
    - anonsurvey -- course personnel can not view both identity of submitter
                    and submission details.
    - anonsurveycred -- same anonymity, but submitter receives 'awarded' for
                        submission
    - surveycred - submitter receives 'awarded' for submission to survey.

Remove some debugging logging used to understand the flow.

BZ 5455 - Raisd the position of the bubbles so that they are on the same
   line as the numbers.

When the target is 'analyze', include the responsetype of the current item in the lonhomework::analyze hash, for use later on, e.g., for scantron grading.

- Fix typos.

BZ 4074  Ensure the bubble lines chunk of the analysis hash gets
keyed by the concatenation of partid.resopnseid.

- BUG#3520, cleanup display of matchresponse is some small ways.

Corrected my own error.

Bug 3176 (Match Response - specifying the print width) is fixed. Additional
attribute of <itemgroup> tag is introduced - TeXitemgroupwidth. It defines the
width of corresponding field in % of the TeXwidth (of line). Example:
TeXitemgroupwidth="30%").

- matchresponse in exam mode looke crappy BUG#3094

- converting to  use push/poprandomnumber

Bubbles do not overlap anymore in the exam mode. Additional space is saved.

Bug 2847  (matchresponse printing location="right" spills into column 2) is fixed. In addition I readjusted the list enironment for the description list which allows to save space.

- BUG#2835, Error either always or never showed up.

- BUG#2551, foil names need to be unique otherwise things go wonky, throw errors if we see repeated names.

- Arrgh!

- how about I test my copy and paste before committing

- 'submission' string for <mathcresponse> now correct
- properly handles <matchresponse> for partial correctness

- fixes <matchresponse> when used in scantorn exam
- <rankresponse> should be better behaved too. but I need to do some testing still

Bug 2541 (matching problem does not print properly) is fixed. Attribute location
in itemgroup tag is now supported.

- stop spamming attempts (Only log a response if there was a response)

- analyze mode is now correct for match response
- now includes a listing of the items in the order presented
- now stores the exact letters submitted

- took a look at all of the analyze outputs and corrected the buglets

- fixing up analyze mode for radiobutton/option/rank/match/image to all use the smae code

- backport 1.27

  in online exam mode
- match/rank getting closer to working in scantron mode

- added &Apache::response::show_answer() to better check for if problemstatus inhibiting should be occuring or not

Bug 2177 (Match items have too much white space) is fixed.

Bug 2048 (Printing match items with concept groups) is fixed.

Bug 1667 is fixed. Internal counter (works only for bubblesheet LaTeX exams) is
implemented.

Changes to print huge problems (no room on single page). Instead table environment module use list-description environment. That allow to avoid a lot of problems (conflicts between dif LaTeX envs).

- consolidates the whichfoil functions and fixes BUG#1439

- unpretty when zero items and editing

- removing lame global

- reintegrating dleted changed from version 1.12

Changes were done according to Ed's desires: 1. Added righttriangle symbol yo any foil in the exam LaTeX mode (lines before bubbles). 2. Spacing adjustment of the text and bubbles is done. 3. Separation of problems with respect to foils (questions) is more clear now.

Enumeration is corrected for exam mode (see notes for optionresponse or rankresponse).

- eliminating an unneeded global

Math expressions in the choice-table converted from line math mode to embedded math mode. It is neccessary because LaTeX does not allow to use line math mode inside of the table environment.

Corrected enumeration for exam bubble mode.

 Corrections done in calculation of possible choices (letters with mark them).

 Correction: array for the printing output has to be cleaned up every time when invoking.

 Improved version of module (looks better on the paper).

Now works in the exam mode. Probably needs some cosmetis additional work (mainly adjustment of numbers).

 Can be printed now. Tested on the simplest examples (2 my own and one Ed's more sofisticated - /msu/kashy/Testing/C2LC/A8matching.problem) - works well. Needs to be tested more and may be corrected for the output having answers.

- Fixes most of BUG#1260, but uncertain how to provide access to table color/alignment/border, leaning towards naming the elements and then letting the instructor use CSS

- Fixes the rest of BUG#1263, can now lock items into positions

- Fixes most of BUG#1263, matchresponse items now randomize

- adding match response handler
