Add halsim unit tests (#783)

Browse Source 
Also adds function that can register all the callbacks at once.
Since all of the callbacks issue a string identifier, it makes it
possible and easy to have one function callback, and differentiate the
path to take based on the string.  Hooking up all the callbacks at once
makes it easier for the simulator developer to know when something was
added to wpilib rather than looking at the commits.
