Ref #763.

Qt4 - Use same type of button in order to not kill the eyes, if you run Plastique or Oxygen. KDE inside :D

Add gzip support to the http access. We never request it, we just know how to handle it if the server forces us to use it (for example Pierre's test page http://www.canalplus.fr/index.php?pid=1784)

POSIX does not define FD_SET for fd >= FD_SETSIZE (=> buffer overflow).
Windows makes FD_SET a no-op if there are already FD_SETSIZE descriptors in the set.

input/meta.c: Don't re-run the art finder if the art was previously set in input_ArtFind. (Should fix youtube.lua arturl).

include/vlc/mediacontrol_structures.h: use u_int32_t instead of uint32_t, since some versions of gcc seem to get confused (reported by Etienne Robillard)

access/http.c: Put cookies handling in a disabled by default option, at least until cookies handling is no more a hack.

Qt4 - Preferences. Fix a small bug in the layout of the complete preferences that happened in the Video section.

Qt4 - make a small comment on how to integrate better the application with your desktop... Yet again the problem with cleanlooks and requests on gconftool.
If you want your KDE4 desktop to tell VLC to use Oxygen, comment the line...

Jokes besides, if ~MainInterface() is called, then p_mi is destroyed, and p_sys->p_mi too. I just hope I am not wrong :D
