fix to compile with cl_visedicts from qw in uq common/quakeio.c: fix bogus string copying
support gzipped files common/quakefs.c: qw_client/cl_parse.c: qw_server/sv_ccmds.c: uquake/host_cmd.c: uquake/menu.c: use "z" in mode flags when reading files uquake/Makefile.in: take cl_ents.c out again (too much work atm to get it to compile)
and fixed up as many f* and gz* calls as gcc found (and, where sensible, grep) Unfortuanatly, demos are broken again.
