Save States: Added PADfreeze calls to PCSX2, though they're currently only implemented by LilyPad. Also fixed a bug where a save state would failed to load when the last plugin's freeze function actually saved something. Minor changes to new plugin API as well. 

Because of a convenient bug in load state function, older save states with no saved pad info should still work.  Don't blame me if they don't, though.
