+ Use the svlc shortcut for skins 2, too.

* modules/gui/wxwindows/open.cpp: simplified a string (sorry for the translations) because it was making the open dialog way too big.

* added an open button

- capture filter is more compatible with ICaptureGraphBuilder2
- some code cleanups especially when dealing with media types

- ordered device supported media types using an arbitrary fourcc preference priority before passing them to capture filter 
- removed assumption where YUY2 chroma was considered identical to UYVY

   a help string

* wxwindows/*: a few cleanup fixes.

* modules/gui/macosx/macosx.m: rewritten a pref-string
* modules/gui/pda/pda.glade: Fixed "VLC media player"
* po/de.po: Updated translation

    - new possible action vlc.mute() to mute/un-mute
    - vlc.isMute is now working well (in a boolean expression)

sometimes not display, although it was known.

  (When you fix stuff you should commit them as well)

* video_output/vout_intf.c: small fix.

  + vout_RequestWindow() will now cycle through all the available interfaces until 
it finds one with embedded vout support.
    This fixes the issue where embedded vout would stop working when additional 
interfaces are spawned after the main interface is started.
  + vout_RequestWindow() now stores the parent interface pointer into the vout 
object for later use by vout_ControlWindow() and vout_ReleaseWindow().
  + added a vout_vaControlDefault() called by the vouts pf_control() when they 
don't handle something.
* modules/video_output/directx/events.c, modules/video_output/x11/xcommon.c:
  + call vout_vaControlDefault().
* modules/gui/wxwindows/wxwindows.cpp: sets p_intf->b_dead when the interface is 
about to be destroyed.

* modules/gui/macosx/controls.m: fix the autogenerated menu.
