Add Wii Remote Support

[bobbydilley]

Add a module which will allow Wii Remote support.

For the moment, this is only for guns and so can have a static mapping from Wii remote buttons.

Should have a static setting that will simply enable/disable:

ENABLE_WII 1

Should simply wait when starting for 1 wii remote, and then wait 30 seconds for another one and if not continue without player 2.

Can use the wii remote vibrate function to simulate force feedback. Read the GPIO and do the force feedback off of this? Will work well for HOTD4. Maybe in a map you could set the force feedback?

WII_RUMBLE_BIND_GPIO 4

Also it has an accelerometer which would work well for HOTD4. This can be statically linked.

Will need to investigate best code for tracking IR point. Use Wii Motion + down the line?
