stats: Implement code to manipulate vector2d stats in python

This patch adds functionality to the vector2d stat type in python. It allows:
    Testing for equality
    Adding two vector2d stats together
    Subtracting one vector2d from another
    Dividing a vector2d stat by a scalar

This funtionality is already present for all other stats in the python module.
