Added Ghost-Editor (based on mobiled doc).
-------------------
- Added mobiledoc editor
- Fixed problems with workflow and auto saves
- Integrated basic toolbar
- Removed all editor related tests, everything bar the most basic acceptance tests will be in the ghost-editor repository.
- Commented out tests which relied on Ember Helpers that are not compatable with mobile-doc, workarounds are inbound shortly.
This is the first integration of ghost-editor. It's styled enough to work, however it is not anywhere approaching something that looks remotely like what the finished thing will be.
Early ALPHA, development build. Tread cautiously.
