ACE compatibility

For ACE compatibility (used in the mediawiki code editor extension),
set the TogetherJS `useMinimizedCode` flag.  Otherwise TogetherJS
and ACE conflict over the definition of `window.require`.
Fix path to TogetherJS icon for editing toolbar.
Update togetherjs loader.
Build user scripts from main sources.

Allow installation of the extension as a user script.  This lets you
play with the code on real wikis, whoo!
I guess I'm really the sole author of this now.
Rebuilt TogetherJS.

TogetherJS sources rebuilt from the cscott/master fork at
http://github.com/cscott/togetherjs, commit

Update VE integration to match latest togetherJS (and latest VE)

This requires some not-yet-committed patches to VE to support
transaction "intentions".
Add .jshintrc
