Title: Bug 864516 - Refresh time displays only when they are visible

- Made the homescreen, lockscreen and status-bar stop refreshing their
time displays when the screen is off or they are invisible
- Fixed timer-leaks caused by starting the same timer twice overwriting
the previous one without cancelling it
- Made the statusbar clock reflect locale changes immediately
