Further optimise hoppers 

Merge the container is empty and move checks when attempting
to pull from other containers, as in both cases the container
needs to be searched entirely anyways.

Use getEntitiesOfClass when searching for entity containers,
so that non-containers are not searched.

For tryMoveItems, merge both the empty and full checks into one
as they basically perform the same logic. Note that it
relies on ejectItems returning true if _any_ item is moved, as
moving items out of the hopper would affect whether the hopper
is full or not.
