Fix vertical scroll behavior and fullscreen iOS

The container div now has the proper css3 100%-45px to compensate for
the toolbar height. Therefore there is no more overshoot scrolling.
Also removed the scroll behavior of the body to make the application
feel more sturdy.
Lastly added minimal-ui to get fullscreen modus on iOS7.1+
Did not see any difference with solution

still remains on iOS at least when viewing in landscape mode.
