Batch Geocoder - overview page

The 'Result Data Content Types' currently listed in the overview page of the Batch Geocoder (in DLV - 5.0.4) need to be updated to match accepted values of current code base.

Examples:
application/x-geo+json vs. geojson
text/html vs. html

Start at the Batch Geocoder overview page and inspect the “Result Data Content Types” section. Compare its entries with the accepted values in the current code base, update outdated values such as application/x-geo+json and text/html, and verify the page reflects the current values.
