Location of some countries is off

[gapan]

In the World overview page, when clicking on a country's name in the table, the map is moved to that country. There is an issue for countries that have colonies all around the world. These include:

• France
• United Kingdom
• Netherlands
• Denmark

If you click on any of them in the table, the map moves at what seems like a random location. Actually it is the location of some tiny island that belongs to those countries.

The correct locations for these countries should probably be (subject to verification):

• France (46.276 2.2137)
• United Kingdom (55.3781 -3.4360)
• Netherlands (52.1326 5.2913)
• Denmark (56.2639 9.5018)

We need to be careful not to break the "Province/State" tab while fixing this, where the location for these small islands or provinces is shown correctly.
