appDisplay: Add threshold after overshoot page switches

Browse Source 
We currently always switch app pages when a dragged app icon
moves outside the grid boundaries, regardless of any previous
page switches. This makes it too easy to switch multiple pages
accidentally, so add a small threshold that the icon has to
move back towards the grid before allowing another page switch.
