AI Refactoring2009Crab

CURRENT:

ai_interface.hpp
ai_manager.cpp
ai_manager.hpp

Move location of info structure from ai_interface to ai_holder (inside ai_manager) (still settable through ai_interface constructor)

NEXT:

ai_interface.hpp

@deprecate get_info and add info() to ai_interface.

NEXT:

ai.cpp
ai_interface.hpp

Change ai_interface methods to use info() instead of direct access

NEXT:

add 'int side' parameter to ai constructor
remove info parameter from ai constructor (it will still be gettable through .info(), even in constructor, for all is needed to get it is 'side' and static 'ai_manager' method)
