Ingame "User map" feature of Eduke32

What the title says. Currently, Raze does not have this but Eduke32 has it (in the new game section under the episodes)

This needs some UI work for a directory browser, but right now the focus is on fixing bugs, so this will have to wait so that a) it can be done right and b) works for all games.

GDX also has something similar, when the others things are sorted I hope to see it in all supported games too.
