Custom clientside compass/minimap image override

[x0rnn]

Similar to how you can use custom location override files (mapname_loc_local.dat), it would be nice if you could do the same with the compass minimap - mapname_cc_local.jpg (draw your own paths, markings, etc.). Or just put a new mapname_cc.jpg inside legacy/levelshots folder and load that. Not sure if it's possible to implement.
