Backbone Conversion - refactoring from FieldView+FieldViewModel-states to createEditable's new states

Please find the patch that refactors edit.js to bind/react to the new "states" in createjs.

Please note:
- Further UI degredation (repadding etc., Toolbar Ops-Toolgroup doesn't consistently show)
- Toolbar doesn't get initialised properly on direct-editables
- No guards against activating other editables, whilst active in one editable
- No guards against activating other editables, when
- There are Jquery errors when you start in "View"-mode and "mouseover" editables due to lacking instantiation of the CreateJS-editables (this will go away when FieldView goes away and editables are instantiated earlier).
- FieldView and FieldViewModel are still in the code, but can be removed once we decide where the FieldDecoratorView and the ToolBarView should "hang" (and we figure out how to keep the predicate information available).

Given this (and my fried brain) I just attach a patch instead of committing this.
