This coverts all of the generators to use python3 style division. None
of these generators are currently affected by this change (generally the
author of the generator has taken pains to ensure that python2 division
does the right thing by explicitly converting between int and float),
but it should reduce surprise to future modifiers, which is good.

v2: - add this patch
