lua multipolygon handling

[pnorman]

Difference found: ways in a MP where inner, outer and relation are tagged with landuse=forest. I don't have a problem with lua's handling, the tagging is unclear. Also, a broken import.

Way in question: http://www.openstreetmap.org/browse/way/42234367

I think the lua handling is correct in this case.

The inner way is also marked as landuse=forrest. So my guess is what happens is that it creates a multi-polygon with the inner way correctly cut out, but then renders a separate landuse=forest for the inner way according to its tagging, making it look like there is no cut out

After the lua script changes from yesterday is this still valid. The lua script now passes all of the multi-polygon tests. So if there are still differences, the test cases need expanding
