[clock app] No way to pause the timer

[Nekhelesh Ramananthan]

The current design of the timer only includes a button to start, stop, done the timer. There is also a button to view the presets. However there is no way to pause the timer.

If the stop button is used to pause the timer, then there is no way to reset the timer and vice versa.

-----------------------------------------------------------
Design Decision:
The main timer button will be used to start/pause the timer. Add a reset button below the timer to as it says reset the timer.

Solution:
Add a button which appropriately resets the timer. The main button needs to be changed to start/pause the timer rather than start/stop. For the reset button, use the ImageButton component which can be found in the stopwatch folder.

Difficulty: Medium

I think a better fix would be to add a separate "reset" button
