Title: closes #786  closes #781 fixed a bug and an inconsistancy in the units lib

closes #786
closes #781

1.) Removed pi from the unitdefaults.lib. Added math.pi to the globals dictionary that is passed to the initial eval() call in _add_units. This way, pi always comes from Python with the correct number of places for that system architecture.

2) Removed m2 and m3 for consistency. One should always use m**2 and m**3.
