Map is now updated with a much better metal map with the
right output for all but a few metal patches, the few that
are not right are within about 0.1 of ota and the terrain will
give 0.2 if you build an extractor on the ground.
I also took the opportunity to fix up some small problems
with the heightmap that cropped up and added the new "water
does damage" tag to the maps .smd file. You will need this
newly compiled version of Spring to enable impassable water, link below.
