* Renamed genGameList to gameIDList to make it match the corresponding
plugin API function name
* removed the detectFunc param from detectGameForEngineCreation,
as it *always* pointed to a straight wrapper around AdvancedDetector::detectAllGames
* as a consequence, removed the various GAME_detectGames functions from the
engines, and removed the detectFunc param from ADVANCED_DETECTOR_DEFINE_PLUGIN
