Street sign colour in agreement with the country

[rinigus]

From https://talk.maemo.org/showpost.php?p=1549254&postcount=239

Currently, the colour of street sign is hardcoded (they show blue on the highway, like in France). But that actually varies by country (Switzerland and Germany have it swapped and use green on highway instead). Do you think it would be possible to extract this information from somewhere ?

At least for Europe Wikipedia has a list: https://en.m.wikipedia.org/wiki/Comparison_of_European_road_signs
(Section Major differences in colour codes)

I think this would be a good first issue for me, so I'll look into working on this one at least for European countries
