disable action in action framework

I’ve had this come up countless time just in the last 24 hours, specifically during testing.  As part of isolating the issue, you have to take out actions, test, put them back in, etc.  You can copy/paste XML but it’s a pain.  The ability to just disable an action would be incredibly helpful.

On a related note, when something wrongs wrong with an action, finding the “error message” is challenging depending on which type of action it was.  Even something as trivial as console.error in the runActionNode would be helpful here.
