Title: Bug 823431 - [Clock] No ringtone and vibration when alarm goes off from screen off mode. r=timdream

Listening "localized" event to replace setTimeout checking mozHidden in init() state.
The patch also fixed Bug 819244 - [Clock] The alarm attention screen uses 24H format but the time picker uses 12H format, which is not consistent.
