Separate out polymost1Frag and polymost1Vert shaders from polymost.cpp and add rules for building in the GNUmakefile.
Additionally, git ignore the shader's generated headers folder. git-svn-id: https://svn.eduke32.com/eduke32@7782 1a8010ca-5511-0410-912e-c29ae57300e0 # Conflicts: # .gitignore # source/build/src/polymost.cpp
