Subject: Moved indicator_led() from Anduril into FSM.  Made it auto-set
 indicator level based on ramp level. Made Anduril configure voltage fudge and
 indicator LED functions based on driver type. Removed "ticks_spent_awake"
 thing since it's redundant.  EV_tick arg does the same thing in fewer bytes.
 Rearranged some clauses in off_state to put events in a more coherent order.
