Hi Jake.

Please use "git format-patch -M" when renaming files.

This patch becomes simple and much more legible.

Subject: [PATCH] staging/skein: rename files and clean up directory structure

Clean up file names and locations.  Get rid of include/ directory and move
those up to the top-level.  Rename files to get rid of upper case.  Remove
skeinBlockNo3F.c as it was unused (temporary file or something?).
