[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).
This looks crazy, the assignment and the mapping from underscores to CamelCase. Can we avoid it? Or just somehow declare the names of the keys that we are interested in?
