Reg. performance: I did not measure it. In most places that I've changed
the clockwise() method was just used to determine a file name, so I/O
performance would be the bottleneck.
I think the Way class is a good place for it, so I've changed that.

There is now only the PrecompSeaMerger which might show a
performance degration, but I don't expect measurable changes.
The area.intersect() methods are copying the ArrayLists much more often,
so one more copy action should not cause problems.
