Implemented joystick input.

Browse Source 
I had to redo how input is done entirely, so more than one source of input can be used for game inputs.

I added new inputs, menu_decide and menu_back. Return and escape still have their reserved status, sending menu_decide and menu_back, respectively. Other keys are reserved too, like arrows, to ensure users can always reconfigure input.
