one-instance fix. It now is disabled in vlc prefs but all windows action

(like double clicking on a file or disc) use the --one-instance option.

People used to running 10 instances of VLC at once should now be able
to do so. Normal people used to running other media players should now
get the behavior they expect (ie: not open 10 different VLCs when double
clicking on 10 mp3s)
