The amount of food gained when eating is used for calculating the food
saturation value so capping it at 20 at this point causes us to get
incorrect results. FoodMetaData.eat caps it at 20 anyway so we're safe to
not do so here.

We know these updates (can) break plugins bypassing Bukkit. They are needed for
smooth updates however. There will be another one right before before 1.1-R1.
