Bugfixes, Tweaks, Usability
#CHANGE: GameObjects no longer accept null or whitespace names. They will fall back to a string spelling "null".
#CHANGE: Changed Serialization Formatter FieldBlockers to be a custom delegate in preparation for later additions.
#CHANGE: The CamView no longer grabs input focus when keys are pressed while the cursor is hovering it. The mouse wheel will still set input focus.
#FIX: Fixed UndoRedo not working on list indices and dictionary keys.
#FIX: Fixed the ColorPickerDialog closing when hitting return instead of just accepting the current key input and applying new values.
#FIX: Fixed the StringPropertyEditor not displaying a cursor for null values.
#ADD: Added ListIndexSetter and DictionaryKeySetter handlers for the respective PropertyEditors.
#ADD: Added CamViewState.SelObj.DisplayObjectName property to provide user-friendly names for certain objects.
