BGE: Adding a Python interface for handling joysticks without needing logic bricks. These new SCA_PythonJoystick objects can be accessed using bge.logic.joysticks, which is a list of joysticks. The length of the list is the number of maximum supported joysticks, and indexes that do not have a joystick available are set to None. This means joysticks can be checked for using something like:

Browse Source 
if bge.logic.joysticks[0]:
    activate_player_one()

if bge.logic.joysticks[1]:
    activate_player_two()

etc..

The interface exposed by SCA_PythonJoystick is very similar to the joystick logic brick except for one key difference: axis values are normalized to a -1.0 to 1.0 range instead of -32767 to 32767, which is what the logic brick exposed.
