Title: Renamed stats functions to lower-case

The functions
Density, Where, Sample, Given, Var, Covar
have been renamed to
density, where, sample, given, var, covar

The functions
P, E
have been renamed to
probability, expectation

with aliases set back to the original names. These aliases exist only in rv_interface and are not depended upon by the internal code.

There is an issue with "var" it overlaps an important sympy function. We could
1) Remove the alias and stick with variance
2) Overlap var in the sympy.stats module and hope no one minds
