Render globe once on the map

If you zoom out so that you can see multiple globe views you will notice that events are plotted more than once across all of those versions. We would like to limit the zoomed-out extent to be only a 360 degree view/extent. Also, we need to enable noWrap: true on the VectorGrid layer so that as the user pans, all of the plotted event markers are clickable.

To do:

• noWrap: true to the VectorGrid layer options, in getVectorGrid() on the map facade.
• Stop the user from zooming out so that multiple world extents are visible.
