System function setup routine

Parameters:
	r4 = 0x05 (Run spell quote routine, skip routine at 141b0c)
	   = 0x06 (Run routine at 141b0c with original parameter values)
	   = 0x07 (Clear r5, r7, and saved stack value, re-set r4 = 7?, then run routine at 141b0c)
	   = 0x08 (Run routine at 141b0c with original parameter values)
	   = else; Run routine at 141b0c with original parameter values

	r5 = ? (see notes)
	r6 = some unit's ID? (see notes)
	r7 = ? (see notes)
