Arbeitsplätze

Regionen haben jetzt immer mindestens 10% ihrer size als freie Freie
Arbeitsplätzt, höchstens jedoch 200.  Das sorgt dafür das die Bäume
nicht alle Bauern umbringen. Diese ernähren sich quasi durch Jagt statt
Ackerbau.
Sinnlose Variable MAXPEASANTS_PER_AREA entfernt.

It's weird. It worked on this PR, probably because it is based on a revision of master where the .travis.yml file already exists. For older PRs that were created before that file was in master, it doesn't work. We don't have many open ones, so it's not actually worth investigating how to fix that :-)
