sandbox, and that I did. It falls back to the older archive when
the template is older then CVS repos.

But along the way I got annoyed with the fact that template instantiation
does not provide a logfile to the web interface. The reason is that
the current logfile stuff is very experiment centric; there has to be an
experiment and an attached logfile. An instance does not have an experiment
until really late in the game so the code was just not bothering.

Anyway, I've started to generalize the logfile stuff with a new table
and the approach that a logfile is named by a random key, and if you
know the key you can look at the logfile in the web (since without an
experiment it is hard to do permission checks unless we make logfiles
uid/gid owned, and I did not want to do that.
