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.

This is still blind fix, don't have windows box to test atm. So don't blame
me when it eats your cat and runs to riviera with your money and gf (and free
to revert in those cases). Don't remember if that check works correctly in
windows side.

I didn't observe any issues with 1.1 or 1.0.5 from file-input, but
lets just set it just in case when we have fps-value.

This should also fix the accept4() ENOSYS infinite loop in httpd
pointed out by Aurélion Nephtali.
