* videoportals.c: Allow using fullscreen youtube URLs and retreive the video's title when possible (still youtube).

FFMPEG's  FOURCC: add NUV codec, Cinepak for fallback and add more fourcc for targa, vixl, divx, SP5x and a few more !

videoportals.c: Add support for google video (this sometimes fails ... the gvp vile referencing an empty url).

Codecs FFMPEG. Add support for DosBox Capture, Worms (Game) Videos, TIFF, SGI ad targa iamges. Tested.

demux/playlist/: New "video portals" playlist demux. You feed it a url from a popular video portal and it'll display the video. Currently only works with YouTube urls but I plan on adding more.

input.c: if available, use p_access->psz_path instead of psz_path when calling demux2_New since the access can change the path (ie http redirect).

Fix segfault upon redirection (test url: http://www.youtube.com/v/zl6hNj1uOkY). (& blame pdherbemont!)

Add a few other bunch of FOURCCs (not all tested). Documentation from avformat/riff.c avformat/isom.c, fourcc.org, http://abcavi.kibi.ru/fourcc.php and multimedia.cx. If this is stupid, revert and tell me.

Qt4 - Open Disc Dialog, finish the disc/track-sub/audio handling. Hide, rename, show correctly the buttons. Some other ui fixes.

Qt4 Detection: Use uic-qt4 and moc-qt4 if disponible. Will help ppl that have qt3 and qt4 installed to build VLC.

* rss.c: Test fix for a bug i can't reproduce (most likely due to a missing 0 at the end of string). See http://forum.videolan.org/viewtopic.php?p=112026#112026 for details.
