Lava buckets not treated the same in dispensers, depending on orientation.

When a lava bucket is dispensed from a dispenser, and the dispenser is oriented facing North, West, East, or South, the dispenser dispenses a lava source block. However, when the dispenser is facing up or down, as can be done in 1.5, it dispenses the entire lava bucket as an item. This is inconsistent with the use of a dispenser, especially since we now have the dropper to drop the item as an entity if desired.
