Added a next question button. You can now move to the next question by clicking on the map, or clicking the new button.

Accuracy of the locations of all cities and landmarks now much improved.
You can now repeat the last game to really help the knowledge gained sink in.
After each "guess", the cities, roads, buildings etc. are shown to help you really get a feel for where that place is.
When the correct answer is revealed, it is placed in the centre. This means that you can use the zoom controls to easily zoom right into the city/landmark in question, without having to pan the map.
Compatible with Mojave Dark Mode.

Fixed positioning of Panama City (thanks for pointing that out Brighton Alex).
Added more World Capitals.
