Making some serious progress with Backbone on the Issues page.

* Removed references to ember.js and also removed old Issues.asmx, no
more services for me!
* Began styling issues list.
* Updated backbone code for Issues. Isssues can now be edited and saved
using contentedtiable, and they can also be deleted.
* Created a global eventbus that can be accessed by all
models/views/etc. to show messages on success/failure.
