world: add __lt__ method to RegionSet

Browse Source 
So turns out genPOI wants to use sorted() so it can use itertools.groupby.

Python 2 somehow just... sorted objects so that groupby (which is basically
the UNIX uniq) could group them properly. Python 3 no longer does this,
so as comparison method let's just compare regiondir strings since that
gives us the desired result.

Fixes #1597.
