0.9.8 - Fix saturation handling and vehicle removal.

Scaling of food saturation values has been completely removed from KitchenSink. When a non-zero saturation scale value is configured, that code sets the saturation of all foods to that value (which is clearly counter to the apparent intention of the code). Fortunately, the default saturation of 0.0 disables the behaviour. We currently have no use for this code, it is missing foods (e.g. COOKED_CHICKEN, RABBIT_STEW and all 1.9 foods), and does something unclear (in the case of slowing hunger) and undocumented. So we're removing it.

A guard was added to the remove-on-exit option so that it only removes minecarts and boats, and not, for example, horses or pigs when exiting a vehicle.
