[tech] Merlo and Mooneye upgraded to Debian Jessie

[David Adam]

I finally got around to upgrading the last two servers to the latest 
Debian release.

Merlo was entirely straightforward and appears to have been fine.

Mooneye went reasonably smoothly, although the change to the Apache syntax 
produced a few headaches, and there are a few services that need a little 
massaging to work properly with systemd. I tried to remove some of the 
cruft from the system before starting, but it's had a long life and 
there's probably a lot of packages that aren't required any more.

Phonehome hasn't been fixed yet, Flame needs kickstarting manually and 
Mailman works (as this message demonstrates) but systemd doesn't agree 
that it's running.
