So now "?compare=<jobset name>" is no longer a hidden feature!
P.S. Encountered this wonderful TemplateToolkit brainfuck again: if
you want to get the number of rows in (say) project.jobsets, you can't
say "project.jobsets.size". That will *usually* give the right
result, except that if there is only one row in project.jobsets, it
will evaluate to 3. Instead you have to use "project.jobsets_rs.count".
