Map Helpers

Adds some nice QoL things to maps.

• If you shift + right click a map on a map in an item frame, it will attempt to place the map inside an item frame relative to the one you clicked on.
• The Map Bundle (crafted with 5 leather in a plus shape and 4 string in the corners) allows you to bundle up a set of maps on a wall in a 5x5 area around the map you click to move it around easily.
