Original commit message from CVS:
Add support for multiple files on command line, and .m3u playlists
(assuming format of .m3u playlist is simply a list of filenames, one per
line.  Comments will probably work, because the file won't be found. ;-> )

Needs to have support for ctrl-c added, so that play can be aborted without
going through whole list of files.
