[exim-dev] Docs for 4.60 - looking great

Just been using the 4.60 docs and I have to say that whatever hoops
Philip has had to jump through (or is perhaps still jumping through, by
the sounds of it) to get an acceptably-working toolchain, the end
result is great. Browsing the PDF version is so much nicer with all the
embedded internal links, chapter information etc. I know that wasn't
the primary goal, but it's a good result all the same.

Thanks for the hard work Philip! Whatever tool is settled on in the
end, if the PDF continues looking like that then it will make all us
who use that version happy.
