Increased burn time (140 frames) for: axe, bucket, grapple bow, hammer, pickaxe, shovel, sickle. So useful items will burn a little bit longer.
Coal will burn for 245 frames and then just burst into ashes and not change into a Burned Object.
Added parameter to 'GetFuelAmount' that specified how much fuel is requested from this object. Oil is now fuel and only the needed amount is removed instead of removing the entire stack when a producer requests fuel.
This was used inconsistently and without regard to correctness, so it is better removed altogether. In case of incomplete objects, the incomplete object always returns the reduced amount.
