Bump hacking to 0.9.x series

Hacking 0.9.0 had a minor bug so require 0.9.1 or higher.

In order to keep this patch to just a requirements bump, ignore new and
stricter hacking rules that are being triggered. Fixing up the code and
turning these on is out of scope of this patch and is for future patches.
