a few corrections to get rpms building. NOTE: THIS WILL NOT WORK FOR -pre VERSIONS because rpm doesn't like `-' in the version string. common/gl_rsurf.c: experimentally comment out some code that /seems/ to fix the r_{water,mirror}alpha bug.
made QF_VERSION and VERSION AC_SUBSTed as well as AC_DEFINED_UNQUOTED quakeforge.spec.in use @QF_VERSION@
add quakeforge.spec to list of files configure is to creat. quakeforge.spec.in: initial checkin. still needs work/testing.
