I never liked it, but with C2x coming out, it's best to handle bools
properly. I haven't gone through all the uses of int as bool (I'll leave
that for fixing when I encounter them), but this gets QF working with
both c2x (really, gnu2x because of raw strings).

Zoid| A good CVAR_ROM example is userpath. The code should read "cvar_t
*fs_userpath = CvarGet("fs_userpath", ".", CVAR_ROM); The user can
override that with +set fs_userpath \<blah\> since the command line +set
gets created _before_ the C code for fs_basepath setup is called. The
code goes "look, the user made fs_basepath already", uses the users value,
but sets CVAR_ROM as per the call.
