PWM blocks

[VonSzarvas]

possible bug

Calling pwm_set in code auto-injects pwm_start after main. Good and works fine.

Then...

Calling pwm_stop stops pwm output and kills the cog. Good so far. Code can now use that IO pin for other important stuff.

Then...

Calling another pwm_set doesn't appear to re-start (pwm_start) the cog. Oops.
