Copper Couldrons and new interactions for Copper Golems

Copper Cauldron would be a block that would be tied directly to Copper Golems. They would perform the same functions as regular Iron Cauldrons except that they would provide additional abilities and introduce new interactions for Copper Golems: Copper Golems could from now on use buckets and Bottles on Cauldrons, after taking from the chest at first they would look for the nearest Cauldron, if the bucket or bottle was empty then Copper Golem could fill it, or vice versa, after that Copper golem would but them to the chest. If no chests were nerby the Copper Golem would stuck and dont do anything.
