Added keyboardControl.py. Not working very well. Does not recoginized when two keys are held down. Probably need to use the pygame.key.get_pressed() function.
Added a number of new keys and methods.

A,Z,S,X for moving the wheels individually. E and Ifor query encoder and
IR values. R for reseting encoder values. Q for stopping the
QuickBotRun.

Commands are sent when received instead of at a given sampling time.
