Due to size becoming an issue, added #ifdefs for Zwobble and Hysteresis patches.
Added ifdef for Filament_alarm_pin; see http://www.soliforum.com/topic/2516/wip-out-of-filament-alarm-autopausesheater-shutoff-when-idle/ for more details on function
Added Auto-Pause function to pause Repetier Host with M600 or Filament Alarm code.
