The default user not a member of group video

[Tommi Höynälänmaa]

It seems that the default user is not a member of group video by default 
in Ubuntu 14.04 LTS. Consequently e.g. the builtin cameras of laptops do 
not work unless you add the default user to the group video. I think 
that the default user should be a member of group video by default.
