Fix even more inspector issues, and some ce ones as well 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 Change-Id: Ibf6b26de299e54ae8688a2653bf5d5538927f8c3
