Fix vertical scroll behavior and fullscreen iOS

(ignore edit use metric and added ios7.1 max screen and mmol for pebble commits, this was a hack for my pebble, but I did not quite know how to easily revert them and hide them for this PR)

The container div now has the proper css3 100%-45px to compensate for
the toolbar height. Therefore there is no more overshoot scrolling at the bottom. ![img_1576](https://cloud.githubusercontent.com/assets/4370175/4022082/76beef2c-2b16-11e4-8727-c4367cd543d1.PNG)

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+:
With minimal-ui activated:

Normal address bar and buttons below:

Did not see any difference with solution:

But maybe added this in the wrong place (client.js). The gray scroll area at the bottom
still remains on iOS at least when viewing in landscape mode (see first screenshot)
