Python Bridge cleanup

Eventually you need to clean things up to stop the external Python process. You do this by sending stop to a bridge instance or to the unique instance. There is also a stop action button at the top right when you inspect an instance.

PBApplication stop
myPythonBridge stop

Check out the Details tab to confirm success, though the default instance will be set to nil by LanguageLinkApplication>>#stop stop uniqueInstance ifNotNil: [ uniqueInstance stop. ]. uniqueInstance := nil .

When the GT image quits, all PBApplication instances will be stopped.
