Tagger now follows the selection in the viewer in realtime with a 300ms delay.
Tagger and it's parent viewer window are now working correctly with FlatView.
Some changes to avoid script errors when a bad button code with the argument VIEWER was used. For example if you use Tagger VIEWER from a button in a lister toolbar without starting Tagger "embedded" (enclosed by square brackets) or without starting a viewer instance first you'll no longer get a script error. If a viewer window exists Tagger will close that window and behave as if the argument VIEWER wasn't given.
