Level minimap in game lobby

[GvardianDLVII]

I often don't know what the map we are going to play, because the name doesn't tell me much. It is not about not knowing the levels, because I later recognize them in-game. The solution could also help in the case of not knowing the map, and would make selecting unknown maps for MP easier.

I would like to be able to view the minimap of a level in the game lobby. There is no space for that, so we would need to find some idea for it. Nice to have: Minimap could have resource fields clearly visible, as well as starting points indicated with numbers in the same colour as the slot's colour.

Maybe convert map overview into ASCII code and put it in the chat :D
