Lines should not be merged if they have different one way properties I
would have thought.

So MapElement.isSimilar() should return false if line.isDirection() !=
otherLine.isDirection() or they both are one-way and they run in
opposite directions. (The method would have to be pushed down into
MapLine, but it is only used on lines anyway).

Don't know if this has anything to do with the disappearing lines
though as that seems a bit odd...  Are the lines really in the map and
just not displayed by mapsource etc.?
