external to the progs file are now malloced and then freed at progs reload.
All that needs to be implementd for gc to work is the scanner and deallocator.
slight api change: the getkey and free functions now take a user data
parameter (which is an aditional parameter to Hash_New.
cmd.c, cvar.c, quakefs.c:
clean up the resulting errors.
pr_edict.c:
use hash tables for lookups of function, global and field definitions.
should speed things up a bit, ESPECIALLY when type checking is enabled.
progs globals and edict fields accessors, but I'm not so sure that's the cause
of the run-time error:
SV_Error: SV_ModelIndex: model progs/player.mdl not precached
Fatal error: SV_Error: SV_ModelIndex: model progs/player.mdl not precached
I suspect I failed to find the spawn function.
