[Exim] Version 3.13 released

I have just put Exim 3.13 on the primary ftp site:

ftp://ftp.csx.cam.ac.uk/pub/software/email/exim/exim-3.13.tar.gz

d4821c12e75814ddeb9a304d58c1e248 exim-3.13.tar.gz

There is also a patch file from 3.12 in the same directory. Details of
the changes can be found in the ChangeLogs file in the same directory
(as well as in the distribution, of course).

This is primarily a tidy-up/bug-fix release. However there are four
small specification additions (which are in fact sort of tidy-up
things).
