horizontal controls correct.

motor 5 was causing trouble with accelerometer, switched motor 5 pins to from 10 & 11 to 14 & 15 which fixed it. Accelerometer code SHOULD be working now. Need to do final test and determine PIN_R.

Added tilt with locking variable to lock the current tilt from RB/LB by pressing A to lock and B to unlock. then changed all PIN_S variables to float so tilt can count by a value less than 1 each loop, giving more precision to lock tilt.

**Need to update Z_PIN code. Need to fix Y_PIN code (probably much later). Also get Arduino working from 5V regulator from breadboard.
