Break apart jquery.gravy.js into a bunch of component pieces.
Some of this stuff (especially in hacks) is probably obsolete, but I didn't

want to get too much into making substantive changes. The only actual changes

to the code are:

* Changing jQuery to $

* Fixing some random issues that jshint pointed out (mostly missing

  semicolons).

Smoke tested modal box, inline editor, and other js functionality.
