Fix System/Running Time to reset the running time whenever a charger or USB cable is inserted, not just when the cable is inserted in the running time screen. Should now make the running time actually be the amount of time rockbox has run since the battery was last charged, which is as far as I can tell the original idea behind the runtime menu.
