Mark3 RTOS Source

-Fixed up some documentation and functionality related to the timer-tolerance feature
-Fixed the semaphore unit test
-Adding python script used to automate the execution of unit tests under simavr

Added "tolerant" timers, allowing for improved interrupt performance (i.e. better power management due to fewer interrupts/CPU wakeups)
