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.

Work-in-progress commit for bug 6209.

Continuing work on jQuery based interface. At this point, none of the
buttons actually function, but the following changes are
notable:

SECTIONS/FIELDS LIST:
-- Reorder now only is allowed along the y-axis, and the "up-down arrow"
   icon serves as the handle by which sections can be dragged.
-- The list is now as long as the number of sections, as opposed to
   using 'overflow-y: scroll'.
-- Hovering over a section name shows a "Delete" icon.
-- New non-functional buttons to "Add Section" and "Revert Order"

ACTIVITY BAR:
-- Activity bar (whose major purpose here is to save) has been put in.
-- The "Save" button becomes highlighted once a change has been made.

--NOT YET DONE--
These are things that I need to do, or have been told about, but
have not yet been touched.
-- Letting lonnet::put manage the freezing of nested data structures.
-- Removing 2.x pseudo-compatibility.

Screenshot attached to bug 6209 on Bugzilla.

Work-in-progress commit for bug 6209.

Features the beginnings of a jQuery-based interface that meshes
with the old interface for the time being.  There are a lot of things
to be prettied and improved, but this is a good stopping place for now.

Work-in-progress commit for bug 6209.

--> Adds capability to delete fields from display for lonsyllabus.
--> Allows basic field title renaming capability.

Work-in-progress commit for bug 6209.

--> Adds capability for arbitrary fields in the data structures for
    lonsyllabus.

DESCRIPTION:

Existing 2.x fields are converted to new 'data.fields.TIME_PROCESS_INT'
DB entries, and a 'data.old_new_map' entry  maps old 2.x field names to
their new 3.x equivalents to preserve backwards compatibility.
Field order and display is maintained by a 'data.fields' DB entry, which is
 a frozen array of 3.x field entry IDs.

When encountering a document with no 'data.fields' entry, the 2.x structure
is converted to a new 3.x data structure as above.  This indicates a
document never touched by 3.x.

Saves of 3.x documents are maintained by updating both the existing
'uploaded.lastmodified' DB entry as well as a new 'properties.last_modified'
entry which is exclusive to 3.x. Mismatched timestamps indicate that a 3.x
document has been further changed in 2.x -- in that event, if an existing
field (ex. 'aaa_instructorinfo') has an equivalent, the corresponding 3.x
field is updated; else the field is appended to the 3.x document and
a conflict fail flag is enabled.

Each new 3.x field DB entry is a frozen hash with structure as follows:
    $field{title} = Name of field
    $field{content} = Content of field
    $field{type} = Type of field, to determine parsing/saving attitude
        - TYPE_TEXT_HTML  -- HTML content
        - TYPE_TEXT_PLAIN  -- plain content
        - TYPE_URL_INCLUDE  -- URLs to be included the course

NOTES:

--> There is still a lot of DEBUG code and output in here.
--> To reset a syllabus from 3.x to a 2.x document, add "&forceflush=1"
    to the edit syllabus page.
--> While "Delete" links appear with individual fields once saved in
    3.x format, these links do not function yet.
--> A temporary function, &print_template_new_fields(), takes the place
    of &Apache::lontemplate::print_template_fields().
--> Documentation will get better over time.
--> Happy belated Valentine's Day.

Refactors nearly-common code located in the templated pages,
into a new routine &print_template_fields() which controls printing
LC_Boxes for fields, and <textarea>s as necessary.  Custom fields
(links to be included, for example), are processed using handler routines
in closures, which are passed in a hash to the routine.

Saves about 140 lines of code are so?

- Backport 1.85 (part), 1.96 (part), 1.99 (part), 1.100, 1.101, 1.103.

- Rev. 1.104 inadvertently added back a line which 1.103 had removed.

-- Upgrading syllabus page to use new CKEditor
-- Move textareas and save buttons  within the LC_Box templates
-- Use rich text editor if HTML is detected, else allow user to
   enable on demand

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

Added &Apache::lontemplate::print_template(...)-call for 'URLs To Include in Syllabus'.

Adds check before calling lonfeedback::newline_to_br to see if
the text contains block-level HTML elements (such as <table> or <p> or <br />).
If HTML is detected, newlines will no longer be automatically converted
to <br /> tags -- this resolves bugs such as 5550, where for
example, inserting a table using the WYSIWYG editor causes
erroneous break tags to be created.

Consistent wording "Course Catalog" -> "Course/Community Catalog"

lonsyllabus
	-encoding the ampersand symbol for valid XHTML 1.0 Transitional

Use cvs diff -w to check, that between this revision (1.91) and the revision before (1.90) there is no
difference except the whitespaces.

code styling. I.e. 4 whitespaces after an if-statement.

Consistent script code style

Size of table is adjusted.

Bug 3102 (Destroy course syllabus doesn't print) is fixed. Now all information is parsed by xml parser for 'tex' target output. I still have to work with some adjustment of the table cells size (doing this right now).

Announcements are parsed correctly for the 'tex' target.

URLs, included in syllabus, are supported for 'tex' target as well.

HTMLarea - only have 5 minutes.

There are lots of odd problems with Mozilla, not just meta-refresh, but
also popup windows and one random segmentation fault.

HTMLArea fields do show up, but
* are too small (just one line)
* generates <br />s that fill up each field
* HTML gets deleted again by clear_out_html

This and the feedback screen are probably enough to play with for now. Both
do not work correctly.

Added 'tex' target in xmlparse call.

allowed=0 for the 'tex' target.

Corrected misprint (missed {) and checked for student's role. Seems OK.

Lonsyllabus.pm now understand what to do for the target='tex'. I've checked it for coorse coordinator and am going to check for student.
