Snoozing!

As a user, I want to snooze alarms so that I don't forget but I don't have to take action immediately

As a user, I want short timers to have short snoozes... maybe 5min default, but if the timer is less than 5min, make it 1min?  I dunno...
OR
As a user, I want two snooze buttons, one for a short snooze, one for a long one

I might try to work on this - will you merge it if I do?
