Testing clustered markers we decided against autoload and want to add a refresh button to load new markers when the map has been moved.
===Requirements
[x] Remove autoloading of new markers when the map moves
[] Add a button which overlays the map and reloads pins for articles within the given frame
[x] Button should appear only when the user has zoomed or panned to change the frame view
[x] Button should disappear on click and only re-appear if the user moves the view again
===Mock and specs

- Button should be normal ButtonWidget (icon, progressive)
- Use "Reload" icon
- UI copy: "Reload results"
Align center within button area as shown below. If not possible, center horizontally and set 20px from top edge of map.
