enabled.

* vcdx/vcdplayer.c: disabled l10n of various error messages
* vcdx/vcd.c: disabled l10n of 2 debug masks. They are horribly to translate and used by advanced users only, who should speak English well enough for this purpose
* rest: disabled l10n of various strings or debug masks which cannot be translated

more to come

mkv.cpp: make the DVD command interpretor global to the demuxer, interpret the command when a button is clicked

- What shall we do for files and module list ?
- Why is there a space after "Audio viualization" in src/libvlc.h ?

* playlist.m: use stringWithUTF8String instead of stringWithCString when creating the Services-Discovery-menus to show UTF8-encoded strings properly
* ncurses.c: don't localise "Ncurses"

* equalizer.m: use preset_list_text instead of preset_list when creating the popup-entries to enable l10n of the presets
* MainMenu.nib: made the equaliser's popup a wider so it fits all l10ns

* BUGS: remove OSX playlist (anyone sees some more issue here readd it with a description...)

- added macosx version detection at runtime with /System/Library/CoreServices/SystemVersion.plist file
- wrapped code

Known bugs: changing advanced view, detection of MacOS X version at
            runtime and many others...

  the method used to resize the image, which can be "mosaic" (the default)
  or "scale". Note that the previous behaviour was always "scale" before,
  but mosaic is much much faster, so use scale method only for fun ;)
* skins2/*: support of the new mosaic method; playlist resize with this
  method is significantly faster!

* Fixes a silly bug in the filling of the NSMutableDictionary that stores the p_item->node correspondance in the playlist
* A side effect of this fix seems to be that adding a directory, deleting it and adding a new playlist item doesn't seem to crash VLC anymore
* Make the currently playling item, as well as its parent items bold
