Commit message

Improved the IDLE performance of the clock app. Added a settings option to hide/show the seconds hand.

Description of the change

Dynamically loads tabs using QML Loaders ensuring there is only one tab in memory at any time. This has improve the IDLE performance of the clock app significantly. It has resulted in the IDLE CPU usage reduction from 2.6-4.0% to 0%.

It also adds an settings option to show/hide the seconds hand.
