Improve loading animation
This MR tries to fix the unintuitive loading animation in knewstuff.
Previously the user was made to wait for the loading animation to be finished if they scrolled even a bit more by accident to view the previously-fetched data which felt frustrating for the user. This MR adds a QtControls.BusyIndicator in the footer to tackle this issue.
