Initializing range var in SurfaceObserver to use this.range instead of null to avoid passing wrong information to onContentChange.
Change-Id: I1d4e3fa2393166dad887077529351a479401bf4b
ve.ce.Surface
* Used getModel() as per TODO
* Simplified code by pre-calculating 2 statements that were being used 4 times each
* Re-structured logic so that simple insertion and deletion are only possible if next and previous have a range, triggering complex change otherwise
* Added some documentation
ve.ce.SurfaceObserver
* Added checks for whether rangy found a branch node within the document or not before accessing it's node via .data() and made it so we are only performing DOM > document range conversion if we did
* Removed some commented out code

ve.dm.SurfaceFragment
* Removed flawed implementation of word mode for expandRange method and made use of new getNearestWordBoundary method in the document model
ve.dm.Surface
* Got rid of useInsertionAnnotations, which allowed disabling and enabling of insertion annotations - this isn't needed anymore because it was just a dirty hack around the improper starting and stopping of surface observer that's now solved more elegantly by emitting lock and unlock before committing or rolling back transactions
* Get annotations from the first character of the selection if the selection is not collapsed
* Only emit annotationChange events if it really changed
ve.dm.Document
* Added getNearestWordBoundary method which performs the work behind the surface fragment expandRange word method
ve.ce.SurfaceObserver
* Allow using an initial selection to avoid the observer thinking the selection has changed just because it started out with null
* Only emit selectionChange event if there was a meaningful change
ve.ce.Surface
* (bug 42279) Only annotate characters if insertion annotations are not empty
* Remove manual locking and unlocking, this is now done inside the change method of surface model
* Provide an initial selection to surface observer when we clear it
* Remove enabling and disabling of insertionAnnotations, this isn't needed anymore
* Stop/start observer on key presses that execute actions as well as those that have no special handling
ve.ce.Document
* Make getNodeFromOffsetand getSlugAtOffset return null when given -1 as an offset

Also:
* Simplified ve.ce.Surface.getLeafNode, which may be better to just be removed and be used inline in the few places it's being used.
* Removed method wrapper for static function ve.ce.Surface.getLeafNode
