Polished Grid example and added a few missing details at
Launcher fragment. Video- and Music examples now also use
an Activity. BackgroundHandler in MainFragment removed.

Removed unused Log-Tag field and added correct background.
Changed Grid Zoom factor.
Moved Grid- and Card example to their own packages and
they now are started using an Activity.
Launcher fragment uses correct primaryColor and its row
has been lowered.
Music and Video consumption example are using Activities
as well. Thus BackgroundManager in MainFragment is
unnecessair, which is why it got removed.
