GuidedResearch Landing Page - reference MapMenu-GR.js

A landing page for GuidedResearch is being designed in order to replace the existing ‘github’ map. This page is located at Main_Page-GR. This page is nearly identical to the Main_Page, however, the list of locations that should show in the dropdown menu (when the List of Localities button is pressed), should reference MediaWiki:MapMenu-GR.js instead of MediaWiki:MapMenu.js.

The reference to the MapMenu.js file is in Common.js, at the very bottom of the page.

I think this is high priority, since the GuidedResearch map currently doesn’t show up in mobile view in production. If we fix this issues, the new landing page can be placed into production and the github version will be obsolete.
