- Added a check when the hasmany read is being performed to see if a duplicate record is going to be added and prevent it.
- Prevented multiple child_removed events from being added when adding light has many records.
- When a light has many is removed a fix was added so that the store reflects those changes.
- Overrode the Ext4.2.1 Model.destroy method so that the indexOf check happens before it is removed. This prevents errors in DataView based views.
