	Used for tuning constants when developing.

	Eg. if you have this constant somewhere that you just can't get right
	by changing it and recompiling all over again:
		v3f wield_position = v3f(55, -35, 65);

	Make it look like this:
		v3f wield_position = v3f(55, -35, 65);
		QUICKTUNE_AUTONAME(QVT_FLOAT, wield_position.X, 0, 100);
		QUICKTUNE_AUTONAME(QVT_FLOAT, wield_position.Y, -80, 20);
		QUICKTUNE_AUTONAME(QVT_FLOAT, wield_position.Z, 0, 100);

	Then you can modify the values at runtime, using the keys
		keymap_quicktune_prev
		keymap_quicktune_next
		keymap_quicktune_dec
		keymap_quicktune_inc

	Once you have modified the values at runtime and then quit, the game
	will print out all the modified values at the end:
		Modified quicktune values:
		wield_position.X = 60
		wield_position.Y = -30
		wield_position.Z = 65

	The QUICKTUNE macros shouldn't generally be left in committed code.
