[PATCH v2 00/10] Add labels support

[Stephen Finucane]

I want to add support for global series states, as noted in #157 [1]
However, to get there we're going to need a boolean open/closed
attribute for 'Patch.state' and to get _there_ we're going to need to
clean up the various 'State' fixtures, as noted in #4 [2].

This series starts work on the latter of these by addressing yet another
issues, #22 [3]. Full details of the feature are provided inline but
tl;dr labels are arbitrary bits of metadata that can be used to
represent some of the more orthogonal states like "RFC" or "Under
Review" along with other maintainer-provided labels. Once we have
support for this, we can build upon it to migrate some of the 'states'
to labels and the 'state' field itself to a boolean field. This is all
in the future though.
