Toolbar configuration improvements

The title kind of says it all. I had to slightly modify the way the view's are created to ensure the location bar and the tool bar are always at their correct coordinates. The default behaviour stayed the same, if unspecified the  tool bar will appear at the bottom of the screen.

Tested on iPhone/iPad emulators with iOS 6.0, 6.1, 7.0, retina and non retina devices, all kind of rotations, with and without the location bar.
