Subject: Changed SaveFileManager::listSavegames() function to be engine
 agnostic. It now returns a list will the full paths of existing files that
 match a given regex. Additionally, modified the 5 engines which use the
 default manager (Agos, Queen, Saga, Scumm and Touche) to parse the filename
 list and mark the available saves bool array correctly.
