UI: Improved "Area Close" Neighbor Selection

The new "Close Area" operator can let any neighbor replace the area to
be closed. This patch improves the selection of the best, and most-
aligned, neighbor. It maximizes the ratio of the shared edge lengths,
rather than minimize the absolute amount of misalignment. This follows
our expectations closer because it takes into account the relative
sizes of the areas and their edges.
