Designate specific chests for Copper Golem to search.

Allow the player to nominate up to 10 specific chests that the Copper Golem can search, ignoring any others. This could be done without needing a gui by right clicking on the nominated chest(s), the Golem, and the copper chest with a copper nugget. It would allow for more creative-looking storage solutions, better use of the Golem functionality, and reduce the redstone requirement for less technical players.
