Switch view mode when clicking hour/minutes

[bjarnef]

When you click to hour or minutes I think the view mode should change (you can do it by clicking cancel button to go back, btw. maybe rename this button to "Back" when it doesn't close the modal), so similar to this one https://github.com/weareoutman/clockpicker - when clicking hour the hour hand is active and when clicking minutes the minutes hand is active.
