Disabled toolbar buttons

[Duane Clark <dclark@akamail.com>]

As Carlos pointed out a few days ago, disabled toolbar buttons were 
still active on some apps. So I did testing with ControlSpy, and matched 
the messages for both active and inactive toolbar buttons. This patches 
matches the messages, and fixes several apps so the disabled buttons 
behave correctly.

Changelog:
	Correct the behavior for disabled toolbar buttons.
