ETS2 - Guernsey Promods Addon V1.1

Changelog v1.1:
Fixed ferry spawn point
Fixed AI cars driving on the right side of the road on the roundabout.

Adds the Island of Guernsey to Promods Europe.
Adds two cities, those being St. Peter Port and Richmond.

I do not plan on expanding the map, as it's already such a small island. I will mainly focus on rebuilding the map when needed.
