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.

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.

--> Adds capability to delete fields from display for lonsyllabus.

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?
