- the adjust-image-filter and the audio-filters are completely useable

ToDo:
- complete i18n support
- video-filters
- loading the settings from the prefs correctly
- probably minor layout tweaks, etc.

   charset the HTML pages will be transformed into (default no transform,
   ie. UTF-8). Call vlc_fix_readdir_charset whenever necessary, the
   http intf should now work under Mac OS X with non-ascii filenames.
   When using the 'add' command (MVLC_ADD), add an extra paramater 'name'
   besides 'mrl' to specify which name to use in the playlist.

   needed. This fixes the directory access module under Mac OS X.

   returned by Darwin's readdir). Probably we should send this upstream.

   under Mac OS X to transform UTF-8-MAC returned by readdir() into
   UTF-8. Darwin always uses UTF-8 internally, so we vlc_current_charset
   should always return UTF-8. Also made vlc_current_charset()
   thread-safe and added a few missing const's.

   UTF-8.

 * move Unicode stuff to a separate file

 * share/html/* : sepcify UTF-8 as XML encoding
 * httpd.c : add a bunch of "const"

* implemented transcoding when streaming -- might need some testing, if anyone on OSX got the time (refs #271)

 * old: convert

* libvlc: Conversion functions (needs performance improvement)
          Convert filenames from command line
* SAP, Skins2: no perform own UTF-8 conversion
* file, playlistold : convert
* wx, winCE : assume UTF-8

I assume the intent was "&= ~" which is not the same.

Needs review.
