Subject: Made thermal regulation adjust smoothly (1 PWM step at a time) to
 make adjustments less noticeable. Added set_level_gradually() and
 gradual_tick() to ramping lib. Not terribly happy with it yet, but it at
 least works in practice. Added extra thermal regulation checks because I was
 running into stupid behavior in edge cases. Increased lowest thermal stepdown
 level to MAX_LEVEL/3 because it was going down way too low before. (is still
 pretty low, but not quite as bad)
