See #3028. Adding the arachni material to unstable. In order to commit
to master, these need to be tested, but I've run into a few small
problems with getting Arachni functional (see
https://github.com/Zapotek/arachni/issues/119 for my gem woes)
I'll loop back around to that.
Also, the arachni plugin includes some kind of autopwn-like feature. I'm
not sure what it does yet but it seems long and complicated, and
probably should be removed at this point, given the lack of the other
autopwners.
