What I Did

Improved ability to trigger saves manually by adding deferreds which are resolved when the save operation is completed
Created a new editable API method called ‘crop’ to tigger a crop externally
Moved the editable image crop into it’s own self-contained method
Improved the destroy method to better un-initialise an editable image in particular
Updated styles to properly show disabled zoom bars.
Updated docs and included an image editable use case (need to do more documentation on image editables)

Implications

Editable is used in a wide variety of places, but I have't significantly changed the operation of the plugin. Should be well tested.

Find or create an image editable region, and try to trigger a crop using the new method with an existing file from the files table.
Try various combinations of crop/non-crop, pre-populated, and image placeholder state with the new crop method.
Ensure cropped files are saved correctly.
