defaults in non-win32 targets. BASEDIR/SKINBASE are gone and the Cvars
which use them in the code are just given the oldstyle defaults now. Use
of "base" is gone. It was a half-assed solution to a problem that doesn't
exist yet. When it finally does exist, we'll fix it right.
ever used were CVAR_NONE, CVAR_ARCHIVE, CVAR_USERINFO, CVAR_SERVERINFO,
CVAR_ROM, and CVAR_USER_CREATED. I kept CVAR_NOTIFY and CVAR_LATCH as
well since the latter was supposed to actually be implemented at some
point and the former would make a useful debug feature.
