Fixed bug 5242 - KMOD_* flags unnecessarily macros; breaks OGRE

Rainer Deyke

While most of the KMOD_* flags are enums, the combination flags KMOD_CTRL, KMOD_ALT, KMOD_SHIFT and KMOD_GUI are defined as macros.  This breaks third-party code that uses these KMOD_* names for local identifiers, such as OGRE.  The correct thing to do is to make them all enums.
