ASkyBlock, AcidIsland, slightly improved radar and playerheads, and optimization
This update adds integration for ASkyBlock and AcidIsland. It simply shades the islands a unique color depending on who is the owner.
I have also added a radar and a playerheads permissions, "cartographer.radar.vanish" and "cartographer.playerheads.vanish" which will allow players with that permission to not show up on the minimap.
I have also made the chunk render queue clear itself if there is no one on the server, which should make Cartographer not use any resources when nobody is playing.
