Fix packaging for OpenStack security release tags

The packager can't handle a git-describe like:

    2014.1.2.1-24-g7405ba6

Due to OpenStack's ambiguous release versioning where the major release
is really 2014.1.

I've handled this by allowing an extra '.\d+' in the patch component, since
there's no way to parse 2014.1 as the major without breaking every normal
package.

Bring back slab as a Hivemind module

The idea now is to create a symlink to the hivemind command called 'slab-test'
and then copy the slabrc into ~/.hivemind/slab-test/config.py

There are a few changes needed to the slabrc. Will push those to our leadnode
repo.
