Get changes in catalog tree to update the UI correctly 

The catalog tree-view now sends appropriate notifiers and messages when
changing data. Either itself or other UIs (like the main asset browser
region) can then listen to these and update.
I try to design this in a way that the views become independent on the
editor displaying them, so the views can be reused in multiple places.
