Periodically update the slices in the dashboard (#374)

Browse Source 
* Periodically update the slices in the dashboard

* Make the refresh interval changeable

* Add the button and the modal for the user to change the refresh interval

* Don't use callback for refreshing

* Randomize to prevent all widgets refreshing at the same time

* Show the loading icon as an overlay when the slices refresh
