This patch merges adjacent external bridge polygons before calculating the angle.

Currently there is a problem where detect_bridging_direction is called with non-empty floating_edges even when the bridge area has no floating edges, such as in the picture below. By merging the bridges first then taking the closing of the merged bridge polygons this problem is fixed.
