Building for python 3 #38

I try to build the pypylon module for python 3.6 on linux. Building for python 2.7 works fine.

For python3 i get the following error:

Warning: Extension name 'pypylon.cython.version' does not match fully qualified name 'version' of 'cython/version.pyx'

I can do some python programming, but i am unfamiliar with compilers for C++. How can I get this running?
