improve Archaelogical data permissions filters

• The Field Investigations resource can stay public, but the mapped information should be private. Again if there is a way to indicate that the information exists without showing it, that would be ideal.
• Areas of Probability should be hidden from map view
  -- almost done, but clicking on a resource still shows the probability areas. this will have to be addressed in map.js, I believe.
• Areas of Probability should be removed from the report map, as well as the legend symbols, but the text information about them can be listed in the report.
• Remove shovel tests from map legend for Archaeological zone (they are now all stored in the Field Investigations anyway).
• Add note to report to direct anonymous viewers to more information if there are hidden probability locations

When I click on an Archaeological Zone on the map view, it still outlines the individual areas of probability within that zone but doesn't show them on the report.

I see this now, good catch.
