Fixed VLC_META_NOW_PLAYING update.

Completed RESET command support.
Updated user agent to "NSPlayer/7.10.0.3059"

 mozilla: don't hold any reference to root object to prevent ownership issues on plugin destroy, just create it and throw it to the wilderness

rss.c: Using [19378] (visible region persitence in freetype font renderer), only display one line of text if the font size option was set.

Change the visible heigh/width only if they weren't set in the source text subpicture. Else use the original values. Could someone with good knowledge of the freetype module (and maybe other text render modules ... if we have any) confirm that this change is ok?

* Fix CFG_PREFIX for config chain parsing and option names (s/rrs/rss/)

Disable ffmpeg GIF decoder. It's currenly not working (doing some weird infinite loop when calling pf_decode_video in src/misc/image.c ImageRead() when using the RSS plugin)

Qt4 - Open. Fix segfault under windows. Still need to find out to hide those buttons under windows. But one at a time.

 - mozilla: I finally figured out why firefox was corrupting memory after destroying plugin (so much fore reference counted objects !)
