Quick patch to make pda.c inteface compile again. It disables the management of the slider on the GUI.

plugin.cpp: some minor cleanup

  - you can specify a comma-seperated list of file-extensions. Files of this type will not be added to the
    playlist when the directory module parses directory contents.
    This prevents duplication of playlist items (both m3u and the real files were being played, or both .bin and .cue were added, therfore playing the same movie twice) and the adding of items that are not really useful to VLC as seperate playlist items.
  - By default are ignored the following: m3u,nfo,jpg,gif,sfv,txt,sub,idx,srt,cue

* da.po: additions to the Danish translation by Jonas Larsen
* Makefile.in.in: small fix, so msgmerge is found properly if it is installed in extras/contrib

* src/audio_output/intf.c: aout_VolumeGet() needs to call pf_volume_get() if it wants an updated value.

* configure.ac: getnameinfo/getaddrinfo/freeaddrinfo are not available on win32 (except on XP/2003 so if we want to use them we'll have to load them dynamically).

* Added a notice of this to news
* Another request from the forum.

* Added --advanced to the "Help Options" as well. It's "duplicate", but it's easier to find now for cli users.
* Restored some add_category_hint so the cli help shows the proper categories again.

* src/input/input.c: use a low priority input thread when in b_out_pace_control && b_can_pace_control mode (avoids using all the cpu time).

* wxwindows: systray integration, with a basic popup menu, tested under
  WinXP and Gnome (introduces two new options, wxwin-taskbar and
  wxwin-systray).

  The icon looks ok under windows but not so good with some gnome-panel
  sizes.

    systems with both 2.4 and 2.5.
