* Export should always be enabled since you can export default tile set
* Fix Select All/None problem

Don't bother testing the reason for exiting the wait condition. If there is nothing to do, it will exit any way.

Fix typo.

Create a "Dead Mouse Area" control to eat mouse events underneath desired area. This is to prevent mouse events from leaking through controls underneath the area.
Replace original "NoMouseThroughRectangle" as this is more versatile.
Prevent mouse through events from leaking underneath the Fly View tool strip.

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
