 * others: removed old printf or unused code.

  the movie. this makes the behaviour more consistent, though the solution
  is somewhat unclean. We should fix this on a higher level but i don't see
  how we could/should.

- cosmetic changes

  useless code as well.

* modules/gui/wxwindows/open.cpp: New "open dialog" that mimics the one from the gtk interface.
* modules/gui/wxwindows/popup.cpp: Started implementing the popup menu.
* modules/gui/wxwindows/interface.cpp: Got rid of the pause button. The play button now acts as a
play/pause button depending on the context.
* modules/gui/wxwindows/*: A few hacks needed to make the win32 version useable.

* modules/gui/macosx/vout.m: Only hide the menubar and cursor if fullscreen
  mode is on the primary screen,
* po/*: Updated po files.

  - oops, i enlarged the timeslider by accident. fixed
* ./modules/gui/macosx/controls.m
  - fixed a mutex_lock issue

     - made the background picture non editable (removes the text cursor)
     - added slowmotion button

  - changed the slower button into a slowmotion button
  - fixed a forgotten mutex_unlock
* ./modules/gui/macosx/intf.m
  - added the slowmotion button
  - some windows shouldn't register in the "Window" menu
* ./modules/gui/macosx/open.m
  - allow multiple file selection

* modules/gui/macosx/open.m: "Open File" is back,
* modules/codec/mpeg_video/synchro.c: Fixed a counting bug.

video). Added some clean up.

stream.

* modules/audio_filter/channel_mixer/trivial.c: Fixed reverse stereo mode
  with MPEG files,
* src/audio_output/output.c: Fixed dual-mono handling.

* modules/access/dvdread/input.c, modules/control/rc/rc.c: fixed typos.

    instead of an error when it can't stat() the device (Closes: #77).

* modules/control/rc/rc.c: Partial fix for the rc interface under win32. On win32, select() only works on
socket descriptors so we don't use it anymore on this platform. Right now we only do a blocking call to
read() although it should be possible to have a fully functionnal interface by using the PeekConsoleInput()
call (someone willing to investigate this ?).

  category.

 * Added tooltips for the subtitles dialog box
 * Added a missing "delete"
 * Added a menu entry to spawn new interfaces (but it's currently
   disabled, due to a problem with the vlc_list_t struct)

interface modules to be loaded in the background when vlc starts. This is
usefull for lirc, logger and xosd. Also got rid of the hacky way the sap
module was inserted, as this just needs to be added to this list now.

 * Cosmetic here and there

  DISPLAY environment variable is unset (gtk like behaviour)

    detection of libdvdread.a, libdvdplay.a and libxvidcore.a. Sorry guys.

  xosd_init returns NULL
  * lib is initialized with configured font
  * more safety checks
