[WIP] Schedule editor angular prototype

The basic functionality of the schedule editor is converted to Angular in this PR.

It's still a WIP since I'm trying to figure out the Jasmine stuff for our CI server, and also looking at the full PR, there is a lot of stuff that has changed that should probably be updated (such as the dollar_j.js).
Sure, I can move it, I was under the impression that gems under the development and test groups wouldn't get included on appliances, but I defer to your knowledge about what actually does get included on appliances :smile:
