Fixes #481, Deleting tag with tag-selected item makes library seem to disappear

Browse Source 
Fixed some subtle tag issues, hopefully without causing new ones:

1) If no tags visible after a delete, deselect all
2) If a selected tag is deleted, deselect it
3) If a selected tag goes out of scope in Display All mode, deselect it (otherwise a tag stays selected after removing an item with that tag from the current collection)
