* modules/control/hotkeys.c: check if there is a vout before writing some OSD, since hotkeys can also be called from an interface now.
* modules/gui/ncurses/ncurses.c: don't add empty ('') entry, in the open function

   playlist is empty

* Better align the iTunes styled slider with other UI elements
* added .spx .ts and .ps fileextensions.

* Set the Id prop on this 'new' file.

            another firewire device in the ioregistry before the iPod.

 libmpeg2 happy.

* Cosmetic fix to misc.m

* src/video_output/video_widgets.c: Added OSD sliders when changing volume or position with hotkeys.
Those sliders are graphical (ie not written with characters) and we can now add others OSD "widgets".

  It doesn't support regexp for now.
* fixed a bug when playlist was empty at start

 if we find them. (Avoid dropping the first frame).

* ALL: bumped version number to 0.7.2.

* modules/gui/wxwindows/menus.cpp: release the wxMutexGui lock before triggering object var callbacks.

    + Use the svlc shortcut for skins 2, too.
