S/Ident 3.1

S/Ident needed a new release to include some additional requester library support that we wanted to use in Webauth 3.2.0, and I took advantage of the opportunity to clean up the documentation a bit. The new version includes the ticket expiration time and the local portion of the principal in the IDENT struct, and the man pages have been expanded and rewritten in POD.

I also cleaned up the S/Ident test server significantly and added a local implementation of krb_life_to_time for systems that don't export that function from the Kerberos libraries.

New version available on the S/Ident page.
