Giacomo's Automatable Cauldrons

This mod allows the dispenser to use buckets on cauldrons.
If the dispenser uses a bucket full of lava, water or powder snow on an empty cauldron, the cauldron will be filled with the relevant material.
If the dispenser uses an empty bucket on a cauldron filled with water, lava or powder snow, the cauldron will be emptied and will return the full bucket with the collected material.
This allows the automation of collecting lava water or powder snow from the cauldrons.
And the lava buckets can become an endless source of fuel...
This mod is not compatible with other mods that modify the behavior of the buckets in the dispenser.
