Updated setup.py to install on Linux

I fixed line in order to allow installation via pip to my linux box.  I change "\\" to "/".

Setuptools documentation states: "Also notice that if you use paths, you must use a forward slash (/) as the path separator, even if you are on Windows. Setuptools automatically converts slashes to appropriate platform-specific separators at build time."   Source: http://pythonhosted.org/setuptools/setuptools.html#including-data-files
