dcraw.c 9.18 (RCS version 1.455)

This is the LightZone version of dcraw.c 9.18. It's got a *lot* of changes in addition to support for a number of new cameras, so there's somewhat less confidence that the merging of LightZone modifications is 100% correct.

I've done a few smoke-tests on Windows XP using the original LZ 3.9 (not the current open-source code). No problems noted with prior test-case Raw files, but Raw files from the Canon 6D don't work as smoothly as I'd like. The lightzone.log shows "Unsupported JPEG process: SOF type 0xc3" and the thumbnail and preview images look like LZ demosaiced them without a Raw Tone Curve. I have a suspicion the two are related.

No surprise, it's also really slow on the huge Raw file from the 6D, especially on my aged computer.
