This requires us to set fullscreen="false" in our cordova apps. Uses the resize event to determine when the keyboard has been shown, then broadcasts an event from the activeElement: 'scrollChildIntoView', which is caught by the nearest parent scrollView. The scrollView will then see if that element is within the new device's height (since the keyboard resizes the screen), and if not scroll it into view. Additionally, when the keyboard resizes the screen we add a `.hide-footer` class to the body, which will hide tabbars and footer bars while the keyboard is opened. For now, this is android only. Closes #314.
