* fixed some minor bugs

 (not well tested)

ES_OUT_SET_GROUP_PCR.
 * net.c: commented out an error message in net_Write.

* modules/demux/dts.c: support for DTS WAV files.
* modules/codec/dts.c: support for 14bits little endian DTS bitstreams.

 * udp: cleaned to use net_*

Render->Blend

    + Control files for a forthcoming official upload.

    + Added proper const keywords.
  * modules/demux/mp4/drms.c:
    + Minor coding style fix.

 * add description to valid values of --align

  official method.
* modules/gui/macosx/playlist.m: Fix Add with options and no enqueue.
* modules/gui/macosx/applescript.m: PLAYLIST_GO fix

 (modplug-xmms.sourceforge.net/)

 The demuxer is selected by extention look up.(mod, s3m, xm, it, 669,
amf, ams, dbm, dmf, dsm, far, mdl, med, mtm, okt, ptm, stm, ult, umx,
mt2, psm), I hope that won't give problems.

 playlist_SetDuration.
 TODO -> add meta info queries trough demux2_Control (a demuxer should
 NEVER touch playlist themself).

problems it is close to correct.

 -> I'm not sure to set correct alpha values and that values are endian.
 safe (both alpha and palette)                                         .

    - subtitle/audio selection works
    - subtitle display works
    - menu fixed.
 Problem:
    - when we see a menu, the currently selected item isn't highlighted
You have to select another to see them. I don't understand why ...
    - manual audio/sub selection is lost when we switch back to the menu.

* www.videolan -> download.videolan

* modules/demux/dvdnav.c: menus navigation seems to be working ok now.

* modules/demux/dvdnav.c: restart the decoders on VTS change only, not CELL change.
* src/input/input_dec.c: fixed the pictures leak work-around.
   Wasn't working before because there always is at least one READY_PICTURE which is the last/currently displayed picture.

 Please test, it may have heavily broken playback of some files !!!

 (not writing); use VarBoolImpl instead to instanciate read/write variables.
 Bool variables can now be combined with VarNotBool and VarBoolAndBool
 (TODO: VarBoolOrBool)
* commands/cmd_show_window.hpp: the commands now call directly
  GenericWindow::show/hide, because the visibility variable of a
  window is a VarBool (so, read-only)
* commands/cmd_input.hpp: added Play and Pause commands
* parser/interpreter.cpp: beginning of support of boolean expressions,
 like "vlc.isSeekable and not vlc.isStopped" (operator precedence is
 not really well handled yet)
* src/vlcproc.*: new variables "vlc.isSeekable", "vlc.isStopped" and
 "vlc.isPaused"
* controls/ctrl_checkbox.cpp: the "state" variable of a checkbox is
  now a passive VarBool, so actions must be explicitely set with
  'action1="..." action2="..."' in the xml file
* removed src/vlcvars.* => "vlc.isMute" doesn't work any more
 (anyway it didn't work well...)
* theme/theme.xml: updated with the new VarBool behaviour

* modules/demux/dvdnav.c: added parsing of DVD style MRLs.
* modules/demux/ps.h: small cosmetic changes.

* modules/demux/dvdnav.c: some coding style butchery and added on-the-fly menus selection.

* configure.ac, modules/demux/Modules.am: added ps2, ts2 and dvdnav modules to the build system.
* modules/demux/demux2.c: added an "ffmpeg" shortcut for the ffmpeg/libavformat demuxer.
