Subject: [PATCH] - remove Windows includes from gl_load.h

This is one of two places that unconditionally pulled in all Windows headers into the GL code.
We also do not need the cruft for defining the standard integer types. GZDoom is C++11 which means that stdint.h will be present. So the madness with the definitions should be avoided to ensure that the types are always the same.
