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.
