Title: Emergency Call on lock screen, finally

- Small modification to `keypad.js` and `keypad.css` so I can reuse them.
- Load the emergency call dialer as an iframe so it would not add overhead to System app startup
- transition, transition, transition
- Improve markup and discard CSS `display` property, use `visibility` instead
