Turn off full screen loader with map interactions

We currently use a full-screen loader during map interactions, such as panning, which can disrupt the user experience. We should see what happens when we disable the full-screen loader when the user is panning around the map and allow the map to populate asynchronously and rely on a success/fail/loading legend to indicate the loading status.

7/15 After talking to Tim it sounds like we should err on the side of performance. If we aren't filtering/hiding the features outside of the Long Island Watershed we should prevent users from clicking on them.
