hotfixes for RAT 1.0

[mohyghb]

1. update the text for empty state world clock
2. infinite snooze does not work, either remove it from options or fix it
3. updated smart voice cancel description to say that it works best in quite environments, and also it cancels the alarm without using the smart wake (the whole point is that you cancel the alarm without touching your phone)
4. If you set an alarm for the same time by shaking the phone twice, it will activate the alarm twice
5. Make the suggestion alarm create use defaults from the user preferences
6. maybe tell them to press power button twice instead of telling them to unlock their phone for the smart object detection cancel
