Other changes in archutil fork

[razor-x]

I've been looking for something like archutil for a while: mainly for the package management side of things. I did end up forking it and making some breaking changes to suit the config automation I'm working on for my personal Arch systems.

Mainly I updated it for Python 3, removed the config file part keeping only the package management, part and switched to a yaml format for the main config. I also improved how it deals with packages from the AUR and added a --sets flag which are one hierarchy above categories.

Let me know if any of those changes interest you and I can see what I can send upstream.

If you're interested in the other automation I'm working on, check out archrc, dotfiles, and the other links on those pages.
