[Wocky] Single sign-on status update

[Greg Hudson]

jabber.mit.edu (which is no longer po15) now supports the GSSAPI SASL
authentication mechanism.

That isn't very exciting until we have clients which support it as
well.  Does iChat have any support for that, or is it expected to?  We
have some Gaim patches from Simon Wilkinson from August, which I've
tested.  They work for GSSAPI authentication but break password
authentication, and have some other issues.  I'm expecting to receive
some updated client patches from Simon soon.
