  do not follow the standard.

* modules/video_filter/clone.c: new --clone-vout-list config option, courtesy of Olivier Aubert.
   Allows to specify a comma separated list of vout plugins that we want to be used by the clone filter.
* modules/video_filter/*: don't forget to detach the vout before destroying it.

  Now a complete redesign of the hiding of the mousecursor.
  - We use higher level functions now (NSCursor).
  - We only hide if the cursor is over our VLCView
  - In many exceptions we unhide. This is mainly for multimonitor support.

* configure.ac.in, m4/*, po/Makefile.in.in: build updated to use gettext 0.11.5 by default.
   This is necessary for the win32 build because old gettext versions do not work on win32.

* configure.ac.in: fixed linking problem with the slp plugin on win32.

* configure.ac.in: use the -O2 gcc option when compiling the skins plugin so that compilation doesn't take ages.
   Also use -fno-rtti -fno-exceptions to save some bits of space.

  Reworked the mouse hiding routine. we were always hiding the mousecursor
  on kCGDirectMainDisplay, but this display is always the one with the
  menubar and not always the one containing our VLCVout.
  This new code takes the vout, and calculates on which displays (plural
  because of possible mirroring) it is being shown. It then shows or hides
  the cursor on all of those displays.
  This should fix #396.

 - doc/skins/curve_maker: files for a VB project for easy Bezier curves
   creation
 - share/skins/default: a default skin. It's an awful one made for
   testing purposes, you'll be warned...

* modules/misc/httpd.c: removed an unused int.

  * ./toolbox: added --update-glade2 flag.

* src/playlist/playlist.c: fixed misplaced variable declaration.

seeks are expensive. (Though not enough)

  - fixed a cosmetic issue.

   - rewrite of code

    ./modules/gui/gtk/gnome.c, ./modules/gui/familiar/familiar.c: added a
    terminating NULL pointer in the fake argv values we pass to gtk_init().
  * ./modules/misc/qte_main.cpp, ./modules/misc/gtk_main.c: these plugins now
    have the "gui-helper" capability.
  * ./modules/misc/gtk_main.c: paved the way for Gtk2.

    defining its fourcc values like us.
