Use independent instance of vlc

[Ashark]

Now when you are sharing screen with vlc-hangouts, then when you want to open some video file, it is played in ShareMe window instead of in separate instance. This behavior is not wanted. Need to explore if it is possible to run vlc-hangouts in a completely separate instance, while the files opened from file manager should use their own and one instance (i.e. second opened file should be played in a window where first opened file was played).
