Started writing CMake macros to generate Python enum classes

* Can successfully find namespaces in Windows
cmake: can read enums.hpp and make list of namespaces
Successful Python enum generation

* Currently runs as part of CMake command, will be moved to build
* Not run on Forms and Ribbons due to nested namespaces
Python enum generation works in Linux
PyPKMNsim: enum classes are successfully generated at build-time
cmake: removed PyQt4 as a dependency for PyPKMNsim

* Packaging library would cause DLL conflicts
Merge branch 'generate_enums'
