player: allow playing directories
If a directory is encountered, replace it with its contents in the internal playlist. This is messed into demux_playlist.c, because why not. STREAMTYPE_DIR could be avoided by unconditonally trying opendir() in demux_playlist.c, but it seems nicer not to do weird things like calling it on real files. This does not work on Windows, because msvcrt is retarded.
