* configure.ac.in: removed useless --with-ffmpeg=PATH ./configure option.

 Proxy aren't yet supported. Use mmsh to force it, else mms will try it
at the end (after mmst and mmsu). Some http url are in fact mmsh but
not yet auto-detected.
 *Please report* not working url and any regression for mmst and mmsu.

* Added support of whell for slider with GTK2

* configure.ac.in, modules/codec/ffmpeg/ffmpeg.c: fixed my last breakage in the ffmpeg detection code.

DO NOT FORGET TO INSTALL LIBMPEG2 AND COMPILE WITH --enable-libmpeg2

* configure.ac.in, modules/codec/ffmpeg/*, modules/encoder/ffmpeg/*, modules/stream_out/transcode.c: fixed detection of the ffmpeg headers/libs when they are installed in their default location.

  corresponding menu. On thy fly filter changes are still not possible.

no way to repair a mp4 file without its header.

* double-click is now implemented

* Added functionnality to region

* oups forgot to commit this one. still the hide/show thing.

* Timer for text control are working badly but it's the first step

and use ffmpeg postprocessing instead of vlc builtins. (It's a lot faster).
