-As much as I dislike the new joypad.set() setup, the least I could do is make it consistent with joypad.get().

--If there is no controller parameter, then all of the buttons are returned as they are stored in the system, just like joypad.set(input) takes button names as is.
--If there is a controller parameter, all of the buttons for that controller are returned without the "PX ", just like joypad.set(input, controller) takes button names without the "PX " and assigns them to the matching buttons for that controller.
--No one approved this change, but seriously, this is common sense. I expect some "change denied" April Fool's stuff tomorrow...
-Implemented a blacklist for ButtonCount. By default, Lag, Pause, and Reset are blacklisted. I don't think any of these buttons should be tracked.
