FreeEMS 0.0.12 Bastard

Changes:

Fixed bug 5 : forgot to add code run time to test for injector hard on behaviour!
Added tooth counters for displaying tooth timing patterns in conjunction with last tooth time stamps at low RPM
Added configurable tooth polarity to rpm/engine position inputs
Fixed a mistake in the code that allowed a ~0x10 to occur (wasn't causing a problem in this instance)
Added PIT based queued ignition functionality which kinda sorta works
