Bundle Unloaders

A bundle could simply be unloaded via putting in a dispenser. While a dispenser empties the contents of a bundle before ejecting the item itself, a dropper would drop the item as a whole, without emptying the contents. This would add to the features of both blocks in a natural evolutionary way. Bundles would have to be changed to give a signal strength of 1 while empty, and 2 when full to keep in line with the way dispensers work now. Right now, they give a signal strength of 2 regardless of state.
