New: Kerberos for Coda!

This is worth a little announcement, although we still have to finish
stuff off a bit.  Robert Watson explored during the last few months how
Kerberos can be used with Coda.  Robert and I have sore fingers after we
spent many hours putting it in the Coda code. We have support for Kerberos
4 and  5 and for old style Coda authentication.

There is one source file which we cannot export from the US/Canada and we
will make arrangements for a proper downloading procedure for this file.
You will also have to set one flag in the makefile and one in a config.h
file (of course this can eventually be automated with configure)). 

Numerous extensions can be considered to make our simple "accept user from
a given realm" policy more flexible (hint hint, volunteers....).  At this
moment we also do not yet have stronger encryption _after_ the initial
binding, but that will come too (and its easy since it is basically
already possible).

Well here they are:
 -kerberos5
 -kerberos4
 -good old Coda
authentication!
