Some classes, not important
Updating the FoodDataBase

Previously, when reloading the plugin it wouldn't update the food
values. Now it does!
Checking, if sender is player

In the "get" command, if one doesn't specify the item he's looking for,
it looks in the inventory of the player. Previously the sender was just
casted to a player, but this could lead to a little problem if the
console is not specifying the item. And the console also doesn't have a
freaking inventory!
Catching a NullPointerException

This is just cheap, but previously if you right clicked an air block it
would throw a NullPointerException. To work around it, I just added the
NullPointerException, which doesn't print out any exceptions or
anything...
