This was cherry picked before merging dev into stable because of
conflicts during the merge.

Conflicts:

	galah/sheep/virtualsuites/vz/vmpool.py
	utils/read_stats.py
Merge branch 'v0.2dev' into brownhead/dev-stable-merge

Made a very rough draft of the interface.

* Docstrings haven't been added.
* Created with minimal reference to the rest of Galah, next step is
  looking at the controllers to see if there's unnecessary functions
  or if I missed anything.
