CommandLine: new command line parser
This implementation behaves mostly identical to old parser. Few observable differences: - There are no option groups (single group is used for all options) - Option --stdout is hidden (it has been obsolete for a long time) - MPD executable name (mpd) is hardcoded for simplicity
