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.
