S/Ident 3.0

Kicked out a new release of S/Ident, incorporating patches from Quanah to support Heimdal (well, making related changes to the changes that he came up with). While I was at it, I included the Perl module in the same distribution (although it's not built by default) and finally renamed requestor to requester everywhere, including in the API.

I really so much want to go through and clean up and make consistent all of the S/Ident code, but since we're no longer doing as much with it, it's hard to justify spending the time.
