#3 extend ID_BLURAY_TITLE_ infos + support mpls input

[Selur]

Would be nice if mplayer could when outputting the ID_BLURAY_TITLE_ infos also output to which playlist file (mpls) the current title matches.
(tried different msglevels but none did show which title belongs to which mpls file)
+
(Alternatively?) It would be nice if mplayer could also play mpls files (like ffmpeg does).

looks like, the problem should can be solved, by adding:
mp_msg(MSGT_IDENTIFY, MSGL_INFO,
"ID_BLURAY_TITLE_%d_PLAYLIS=%d\n", i + 1, ti->playlist);
to stream_bluray.cs in line 322
