Comment 1 for bug 1803001

Thanks, looks like you helped Texas_Ace quite a bit. :)

This branch will need some cleanup before merging though, to clear up a few things:

- This makes click-for-off override the memorized level, even if it was accessed from a shortcut.
- Since the new definitions are mutually exclusive, it should probably have two defines instead of four.
- Also includes some unrelated changes:
  - Full turbo from off
  - PWM table compression
  - The beginning of a patch to disable stepped ramping
