fixed setup.py to not use relative paths blindly, added some git conveniences
added setup.cfg for python module, updated main CMakeLists.txt to include .proto generated headers when install headers is enabled, got rid of fancified pathing in setup.py, was getting squirrely
added .proto headers too early in build
scratch that, reverting
using setuptools_cython in setup.py to simplify that whole mess
setup cmake to build python .proto files, vendoring rpcz_pb2.py into python/rpcz/ though, couldn't get it included with cmake/setuptool
updated .gitignore and set generated source install DESTINATION to ./
Merge branch 'release/0.9.1'
