Fixed an issue when importing a tile set that already exists would cause an error. When an imported set has a same name, it is renamed so the name is unique. The original logic had an error and was allowing the "new" set to be added with the same name, which would cause an error. In addition, if a new tile set brings no new unique tiles, it is now ignored.
Fixed an issue where the progress was based on the total number of incoming tiles but this total can change if a given tile already exists in the database (it is not added).

In Qt 5.10 QGeoMapType need QGeoCameraCapabilities as argument
E.g: https://github.com/qt/qtlocation/blob/2b230b0a10d898979e9d5193f4da2e408b397fe3/src/plugins/geoservices/osm/qgeotiledmappingmanagerengineosm.cpp#L167

For whatever reason, showing the dialog through a function causes a crash in QML (undebugable--new word!)

Internet available now has a signal

This way:
* GCS location is shown
* It follows same centering semantics of FlightMap
* Note: Vehicle is not shown

Switch test from 8.8.8.8:53 to "www.github.com:80"

Experimenting with Esri

Added top/bottom alignment state to map scale
Allow disabling instrument widget altogether
Added an otherwise redundant row to PlanToolbar so it matches the same button position as the main toolbar
Fixed typo (Math.max()) in ScreenTools
Fixed Javascript Exception in OfflineMap
Increased the import window size in OfflineMap
Added function to MainWindow to disable toolbar for a truly modal dialog
Added code so clicking on an open toolbar indicator will cause it to close

* Map type now set from General settings
* No map type control in maps

Add placeholder for device import/export.
