better the administrative capital, Porto-Novo.

- Black stars for cities with embassies.
- White stars with black border for capital cities without french
embassies

and cities are both squares :

- Black square for cities with french presence
- White square with black border for other cities

Changing shield-text-dx and shield-text-dy for towns because of the new
icon

Allow the capital cities without embassies to overlap also, like
embassies (mainly for Benin, Cotonou and Porto-Novo)

Reduce the shield-size of embassies, capitals and intermediate a bit for
small zooms to prepare the visibility of the regions soon.

On zoom 9 and 10 make bigger the shield size for all

Smaller size on zoom 6 - 8
Bigger wrapping to allow more visibility
Add a label position tolerance, label of provinces are not POIs, their
placement can be moved a bit

At zoom 9 :
Bigger size for font and bold font, really better visibility

#place[type='city'] and #place[type='town'] without shield should begin
after zoom 10

Only show villages at zoom >= 11. Avoid to mix label with points and
labels with texts for human settlements. We don't really need to show
them up before zomm 11.

Better size at different zoom levels

around cities
