Add new Notifier event types, 'collection-item' and 'item-tag', which send id pairs, e.g. adding tagID 2 to item id 1 would trigger ('add', 'item-tag', '1-2')

Browse Source 
Similarly, removing items from collections now uses collection-item remove instead of item remove

This was done to prevent some problems that resulted from the tag selector using item modify events to update itself (which caused the items pane to refresh itself before itemTreeView.notify() got a chance to do the things it likes to do).

This should also help out utility writers.
