Map on results page should be zoomed in to the area selected

[mariongalley]

We need to define a 'correct' amount of zoom surrounding the area(s) selected on the map so that when you pick e.g. a country or region, it is zoomed into that area. I'd guess users probably want it to be zoomed in enough for the LAs to appear. And when you pick an LA it should be zoomed into that particular LA.
