* added missing #include "leak_dumper.h" to new cpp files

* fix for map names not being formatted (and replaced explicit loops to do the same to tileSet & techTree)
 * fix exploration state for fog-of-war off & multiplayer (note: also turns off for AI, diff. behaviour to before)
 * added fogOfWar to GameSettings and added to cutom game menu/menu_state_custom_game.cpp
