quakeforge/tools/qfcc/source/pr_opcode.c
Bill Currie bbc97079e0 pr_comp.h: 
define PROG_ID_VERSION as 6 and redefine PROG_VERSION as 0x00fff001
	(0.fff.001) for the new qc features.
pr_edict.c:
	support version 6 and version 0.fff.001 progs
qfcc.h:
	add version field to options_t
	add min_version field to opcode_t
pr_opcode.c:
	set the minumum version of each opcode (gee, that table is getting ugly)
	filter out opcodes with too high a min_version when initializing the opcode
	hash tables.
qfcc.c:
	update help output.
	accept --id to limit code generation to id compatable (ver 6) progs.
	default progs generation to 0.fff.001
