Updated ButtonMotorControl VI + added some Compressor code

-ButtonMotorControl - now Motor Speed is an input as well, instead of
changing it in the VI itself (so you can have diff. speeds for diff.
motors)
-PickupAngle motor is now 0.75 speed, Lifter is 1
-Inverted the up and down values to fit the motor orientation (instead
of inverting the joystick buttons like before)
-Added Compressor code (disabled in Periodic Tasks 10ms)
