when one of these three popupmenus is shown, there was no way to hide it
 without first executing an item in the menu. (see for instance, earthox skin)

This patch ensures that the usual way to hide the default PopupMenu is also
used to hide any one of these other three popupmenus.

This patch
   - ensures no accumulation of QMenus
   - removes the root Widget for dialog_provider
   - unifies all four popupmenus in term of API

For skins, it also fixes bugs when trying to hide popupmenus
(Video, Audio and Misc). These were never implemented at the
 qt4 level, but used at the skins level.

Especially when playlist is opened.

I know spaces are expensive in a source code...

Fix #3497
See http://msdn.microsoft.com/en-us/library/dd407253%28VS.85%29.aspx?ppud=4 for more information

This patch ensures that _all_ menus/actions have got a parent widget that
is guaranteed to be deleted.

This patch
   - solves memory leaks for menus and action(children)
   - solves a side effect (crash) pointed out
     by 193e6eac where
     some vlc objects were no longer properly released for lack
     of a clean menus/actions release chain.

Do not show ":" separator if album missing.
Show album even if artist missing.
Optimize a little bit.

OS X framework: fixed packaging failure, which prevented Lunettes execution on some setups due to a failing libvlc initialization

especially, also detect material recorded at the stream filter level

same options needed for vlc_accept as those for vlc_socket

some video seemed to go pass and sended to last.fm otherwise.
