(optionally?) load all datasets on search map by default

[srstsavage]

It would be nice to have an option to load all dataset locations on the search map by default/on first load. Users are getting confused and thinking that there's no data in the dashboard, and it takes them a while to figure out that they need to hit the Search button to see results.

If this isn't feasible, having some sort of alternate landing page that just listed the available datasets without any digging required might work.
