Custom /hansard/<id> view for ZA
Round-trip from /person/slug to /hansard/123

includes templatetag to resolve speaker to person, perhaps this should
be moved to better place
Permalinks and speech detail page
Cleanup of sayit urls under /hansard for ZA

Clean up the kludgy sayit url resolution I'd made, and use the new
sayit namespacing under 'speeches' instead.

The name resolution back to pombola person is done with a redirect,
which does have a few disadvantages (and also needs to be removed
if there's no candidate, to avoid a 404 page)
SASpeakerRedirectView is now a RedirectView

(e.g. moving away from SpeakerView, as per matthew's suggestion)
Doc fix for Person <-> Speaker resolution
Replace speechlist_name with of '{list}:section-view'

as per matthew's comment
Merge remote-tracking branch 'origin/issues/876-hansard-index-page' into issues/897-custom-hansard-view
