ai_manager.cpp
ai_manager.hpp
formula_ai.cpp
formula_ai.hpp

Remove info parameter from ai constructor (it will still be gettable through .get_info(), even in constructor, for all is needed to get it is 'side' and static 'ai_manager' method) Move location of info structure from ai_interface to ai_manager. Change ai_interface methods to use info() instead of direct access
