Make PonySay available as Python module

[dluciv]

E.g. it should be available to do (from any Python program) as follows:

import ponysay
ps = ponysay.Ponysay()
... the stuff in pythonic way rather then in shell way...

P.S. Issues about pip and PyPi are likely more general than this one.

Sounds like a brainstorm, but supporting Windows will be also nice =)
