Subject: refactored how interrupts work...   set a flag and return
 immediately,   then handle the actual logic later during a less-critical code
 path Enables smarter responses to standby wakeups. Seems to fix missed button
 presses during standby,   and most of the too-fast sleep ticks. Also
 eliminated waits from button state measurement, so it can happen easier
 during standby.   (also eliminates the chance of an infinite loop on
 extra-noisy hardware) Also might improve timing-sensitive interrupts like
 attiny85 PWM channel 4,   or a PWM-DSM hybrid technique I'd like to try.

BUT this change also appears to break the thermal sensor, so that needs to be fixed.
