Adding setting / property for geocode lookup accuracy #14
Description
In some cases the preset minGeoAccuracy: 'ROOFTOP' (in Ext.ux.GMapPanel3.js) does not generate a latitude / longitude. Setting the value to for instance 'APPROXIMATE' solves some of these issues.
Therefore it would be nice to add a system setting or a TV property (so you can override on a per TV base) for the minGeoAccuracy.
