Distributed map popup "unknown map implementation:" on new install
Description
Visiting the distributed map on a system with no gwt.maptype value set results in a rude and unhelpful popup that reads simply "unknown map implementation:". A new user just plinking around the interface may think that this indicates something is wrong with the system – I get asked frequently about this by new users.
We should set the default value of this property to "OpenLayers" in opennms.properties since that implementation does not require an API key (the OpenStreetMap Nominatim geocoder requires an e-mail address, but this is not the same thing) and is the same tile source already used by the new geo-map in 1.12.
Environment
Any system whose "gwt.maptype" property in opennms.properties is set to an empty or invalid value -- the shipping default is empty, so a newly installed system will suffice.
