Title: Bug 842558 - Tapping the top of the screen causes the utility tray to appear and slide out immediately

Fix for [#842558](https://bugzilla.mozilla.org/show_bug.cgi?id=842558). This patch adds the `utility-tray` class to the screen only when actually making a drag movement from the top of the screen rather than from `onTouchStart`.
