pass through not supported

[dbquarrel]

Seems to fail out on uncompressed archives. My project has about 15 gigabytes of data that needs to be zipped and transferred. This data is image related and encrypted already. I was getting failures with kUnsupportedMethod when running in pass-through mode (-mx0) while compressing. The solution for now at least for me is to compress my archives, but compressing 15 gigabytes of encrypted data takes hours instead of a couple of minutes in pass through.

It would seem to be a trivial case to add "no compression" as an available compression method. From what I can tell it has to be explicitly compressed with LZMA or LZMA2 for this kit to work.
