EXPERIMENTAL

Removed X event loops from GCPad and Wiimote plugins, and implemented an asynchronous check for keyboard and mouse buttons.
Also added an X event loop in core that handles events while the emulator is paused.  Prevents unexpected behavior from events that occur while the emulator is paused.
Now there is only one event loop running at a time (besides those hidden in SDL).
I will revert this commit if other devs are unhappy with it.
