* changed wizard-shortcut to shift-cmd-w
* re-ordered the file-menu slightly

Thanks to thedj for pointing most of that out.

* This fixes the drag'n'drop from items from the finder in OSX
* Not sure PLAYLIST_END is handled correctly in every case (don't know enough about adding modes to judge)

  (btw. this makes a certain sample work that didn't work when it was fed trough our h264 packetizer. before it would crash. This indicates there is an error in our h.264 packetizer)

  We were setting play/pause and seek commands non-aggregate, while we should set them aggregate.
  Fixes #340

   application data directory.

   Fixes #337.

* modules/access_filter/timeshift.c: complete rewrite. Configurable granularity so it doesn't waste as much disk space + deals with full disk by overwritting oldest data.

   now be much more stable.

     - Fixed a selection bug in CtrlTree
     - Simplified some algorithms using helper methods
     - A few coding style fixes

* configure.ac: allow building vlc's mozilla plugin against gecko-sdk. Patch by Diego Petteno (flameeyes at gentoo) + modifications by me.

* modules/gui/wxwidgets/preferences.cpp: unicode build fix (bugzilla #2117). Patch by Diego Petteno (flameeyes at gentoo).

* include/vlc/vlc.h, include/vlc/control.h, src/control/util.c: introduced vlc_int64_t in the libvlc headers instead of using long long which isn't portable + fixed a function prototype in control.h. Thanks to Brian Robb (vascy at hotmail) for pointing out the problem.

Remove some useless code
