Tidying spacing on world locations page

I have made basic css updates to tidy the spacing on world locations pages and 1 small change to documents block on orgs page.

I think there's a lot more that could be done to tidy (spacing/design wise and code wise) all page types.

The header for now has had some padding added to it (discussed spacing with Stephen). But will no doubt need revisiting when the links top right are in place. I think a separate story to align (design and code) all different types of heading blocks is needed.
