Get rid of PyInt in Python 3

It looks like for Python 3 you redirected a few API calls for PyInt to PyLong functions. There was one other API call to PyInt that was missed and caused a crash when it was called.

Before I realized that it would probably be easier to redirect that call too, I went and just removed everything that had to to with PyInt when compiling for Python 3. 

I am brand new to Python, so I don't know how to test this very thoroughly, but it fixed my crash and seems to work with what I am doing so far.
