JSON array with null or undefined value will now skip the offending item, and proceed to load following items. Added tests for null and undefined array elements.
* Testing handling null and undefined id in block definition.
* Adding test utility function to capture console warnings.
* Test assumption that creating a simple block will not cause a warning. This is assumed when later checking warning counts.
Adds test blocks to demonstrate capabilities. Stopped short of adding BiDi override characters.
I added to the toolbox category "Images". It isn't really images, but it didn't seem worth making a separate category at this stage.

This commit adds a fallback when attempting to merge events that
collide on a hash but do not actually merge. Previously, the latter
event would be dropped.
This also fixes a minor UX problem where moving the isNull check into
the merging loop resulted in extra events in the undo queue that
served no purpose and required multiple undo operations without visual
feedback.
Fixes#1373
