I've mostly styled the /Widget/TitleBoxes, but they still need
to be colorized according to type (and this needs to be synced with
history).

A lot of form elements still need styling because they don't have appropriate
classes.  These would be done already if I could use CSS3 attribute selectors,
but alas, I can't.

A few JS improvements plus general cleanup of HTML as I go along.

I still have to correct for a few IE bugs.
