Full hour reminder

[morfikov]

There's one thing I really miss when I switched from a regular wrist watch to a "smartphone watch", especially when i think of the digital watches. The watches had a feature to beep at full hour, every hour. It would be nice to have such beeper in Simple Clock. It also would be nice to have a configurable period of time when the phone wouldn't make any beep sound, especially at night. And also a user could use different beep sound, for instance a one longer beep, or two fast beeps.
