macosx: added an option to automagically save the equalizer status and its settings (default enabled). Code cleanup.

X11 video output: give the focus to the video window when going fullscreen, that helps having the video on top of other windows in some situations

Note however that LUA should still be moved to poll().

services/discovery/shout.c: Add a French TV service discovery. For now it only has C+ and les guignols.

Canal+ lua demux. Example use: vlc --http-forward-cookies "http://www.canalplus.fr/index.php?pid=1784"

* include/vlc/mediacontrol_structures.h: revert [24391] as it breaks compilation (nightly builds and for me in cygwin as well). I'm curious why in the initial commit only this single occurance had to be changed and not all the other ones in the code. So I think it's safer to revert for now..

New;
- Mozilla/firefox toolbar for Linux
- Play, Pause, Stop, Fullscreen and Mute buttons
- Timeline, you can click on any place in the timeline and the movie will jump to it

Fixed: 
- Coding style, readibility
- Maximum 80 characters per line
- Major memory leak, due to not releasing image data

Known bugs:
- updating timeline not working well because callback function not working "libvlc_event_attach......"
- white line below the toolbar
- play/pause toggle not working well because ticket #1065

osx: use dmg-creation code from the 0.8.6-bugfix branch to provide reliable NBs (to be reverted as soon as the existing script is fixed)

Ref #763.
