I just made it in more cleaner way. Now there is Engine_Empty class
which does nothing but shows that message. Also there is
Engine::GUIErrorMessage() method which inits gfx and shows same message.
I.e. if you engine detects game in Engine_BLAH_create(), then return
instance of Engine_Empty object. Arguments are these:
OEngine_Empty(System *syst, const Common::String msg = "No valid
games were found in specified directory.")
If your engine detects game later, say in BlahEngine::init() method,
then just call Engine::GUIErrorMessage(const Common::String msg); and
return 1 from init() method or from go() method.
