vcmi/AI/VCAI/VCAI.cpp
Michał W. Urbańczyk f8a27a9fdb * Moved CConfigHandler from client to lib, CMake/Makefile need updating. I believe other projects besides client also need access to settings. (surprisingly there was a "server" category used only by client... and now VCAI.) 
* It is possible to set the battle ai that'll be used by neutrals by typing in VCMI console:
setBattleAI <AIName>
VCAI also respects that setting and uses given AI as its battle back-end.
