Turn prvm_edictset into prvm_edictget when 4 args

[Baker7]

// prvm_edict.c

static void PRVM_ED_EdictSet_f(cmd_state_t *cmd)
{
	prvm_prog_t *prog;
	prvm_edict_t *ed;
	mdef_t *key;

#if 1
	if (Cmd_Argc(cmd) == 4) { // Baker: Turn into prvm_edictget with 4 params
		PRVM_ED_EdictGet_f (cmd);
		return;
	}
#endif

So when you are in the console ...

prvm_edictset server 24 scale // Uh, I forget what the scale is, let's press Enter and see current value

0.20003

Ok it needs larger ....

prvm_edictset server 24 scale 0.4 (enter)
