- huge cleaning of the interpreter; all the variables are stored in
 the container VarManager, and can be retrieved by their name (with
 type checking if needed). Some variables are still owned by VlcProc
 for technical reasons (their interface is not compliant with normal
 variable, because of the "updateVLC" trick)
 - replaced double by float

 	       put 1% instead.

(4:3 is one of the few *not* in this category).

Allow user to override subtitle scaling via sub-aspect-ratio, 0=auto
or what we do now. 1=do nothing.

* New playlist import/export system:
   -export plugin in misc/playlist (contains one module for each file type)
   -open plugin = special demuxer2, that can be opened from the command
    line or the graphical interface.
  NB: the demuxer "playlist" is forced to earn speed, but this does not
  work yet, as we have a demux2

* modules/gui/wxwindows: use the new import/export.

* src/playlist/group.c : fixed boundary check

* src/playlist/item-ext.c: correctly reset stuff when clearing the playlist

  (At the moment the whole playlist is rebuilt each time; the link
  between the list control and the list variable should be enhanced
  to avoid that)
* src/window_manager.cpp: raise all the windows when one clicks on
  any window (the previous behaviour was too confiusing)

 * removed unused variable

 * fixed a segfault when the 'f' button was pressed with no item playing

* Added SORT_ID
* remember last sorting and ordering in playlist struct

Some bugs when 16:9 scaling in ogt_parse.c and cvd_parse.c

  Changed playlist_SetDuration.
* changed SORT_NORMAL SORT_REVERSE into ORDER_NORMAL ORDER_REVERSE

  - Added the duration column
  - Added a 'surpress error dialog' option to the dialog
* ALL: copyright year and author changes

  src/misc/variables.c: Added a VLC_VAR_TRIGGER_CALLBACKS action
* src/libvlc.c: You can now change verbosity on the fly by using the "verbose"
  variable of p_vlc. -1 == quiet

* src/extras/libc.c: return result in vlc_asprintf().

* ALL: added vlc_asprintf() to our libc.

  You used vasprintf but used asprintf paramaters. Which one do you want to use?
  i changed to asprintf now.

  * ./modules/demux/mp4/mp4.c: if sample has not been decrypted, do not
                               pass it on to decoder.

* ffmpeg.c: 0.4.8 ifdef'ing

* modules/demux/mpeg/Modules.am: forgot to remove private.h.

* modules/demux/mpeg: fixed latest changes to mpeg system demuxer (dvd playing was broken).

* modules/codec/ffmpeg/video.c: setup dummy palette to avoid segfaults with some codecs.
* modules/codec/ffmpeg/ffmpeg.c: more fourccs.

 * add fourcc "smc "

* modules/codec/ffmpeg/ffmpeg.c: compilation fix for ffmpeg 0.4.8.
