New DEBUG state.

Changes:
-Moved debug states around so that the characters read are in
alphabetical order.
-Added a new debug state:
-t : Test the pins using the SoftPWMServo library.
-Changed the led array to use 16 individual pins instead of just the PWM
pins.
-Added a comment to remind us which pins are PWM by default.

-Added comments testing a new PWM library, found here:

Will uncomment once I can get it to work with the pic32 architecture.
