Commited my new wiimote plugin work so far. Some code was copied from the current wiimote plugin. I have cleaned up most of the functions, but there are still a bunch of unused structs and stuff that I need to clean up.

Moved ControllerInterface to InputCommon. Moved GCPadNew GUI/Config code to a new project, InputPluginCommon. It is used by both GCPadNew and WiimoteNew. I hope that I included everyone's fixes to GCPadNew and ControllerInterface.
