- already had methods for various kinds of broken-up data, but
not one for plain "region/zone" strings; having this makes
it easier for QML to report a zone.
- use the region/zone method from QML, so that clicking on the
world map updates the actual TZ in Config.
fully implemented:
* loading of a live map, ESRI based, zooming & dragging possible
* IP address is translated to map coordinates
* loading of the map centers to the obtained coordinates, with a marker set
* coordinates are translated to a timezone, label visible at bottom of the map
* mouse movement will show changing coordinates
* clicking on new location will center map there, marker moved too, timezone label adjusted
* hasInternet switch set to either load Map.qml or Offline.qml
not done:
* get hasInternet status
* fill the fine-tune 181n.qml with proper locale & language data
* connect the obtained timezone to globalstorage
comments are left in the various files for what needs attention/changes
