Add some more files from http://www.fastcgi.com/dist/ that were recovered from archive.org

This just adds the dist/ directory, but it's done as a git-subtree merge so that there is a record of the script that I used to fetch these files (and their hashes) from web.archive.org. This way, you don't have to trust that I didn't surreptitiously modify these files.
