Add support to speed up copper golems

[PanSzelescik]

I don't really know what the copper golem code looks like, but it would be nice to have configurable (based on this article):

• It can pick up at most 16 items in a stack at a time
• The Copper Golem will visit at most 10 Chests or Copper Chests in sequence to try to pick up or place an item
• If no matching chest is found the Copper Golem will idle for 7 seconds before trying again
• The search area for chests from the Copper Golem's position is horizontally 32 blocks and vertically 8 blocks
