DFInput: Implement SDL2 GameController support.

This change allows the user to use SDL2’s GameController API instead of the Joystick API.
The Game Controller API maps the buttons similar to an Xbox 360 controller, so some tricky mapping needed to be done.
Note that it currently only supports OS X.
