[mkgmap-dev] Commit r3759: Don't add way with junction=roundabout as routable line when it has no highway tag.

Version mkgmap-r3759 was committed by gerd on Wed, 18 Jan 2017 Don't add way with junction=roundabout as routable line when it has no highway tag. This catches wrong tagging like relations with type=multipolygon junction=roundabout so that the ways created by the MultipolygonRelation code are not added as roads. http://www.mkgmap.org.uk/websvn/revision.php?repname=mkgmap&rev=3759
