added embedded video to homepage

Added styles for spacing and fluid grid behaviour
Revise pinned requirements for sayit & co

* Pin sayit to 'pombola' branch, as that is a branch specifically
designed to always be deployable for pombola.

* Pin za-hansard to 'master', as za-hansard only integrates with
pombola, so master should always be deployable.

* Add -e flag for above, to make sure they are re-installed on change.

* NB: Retain specific commits for popit-django and popit-resolver
Don't import Places that are Wards

These are just municipalities with a number afterwards, so just
clutter the search results.
Allow a deeper zoom on the map page
Correctly capitalize 'Parliamentary Monitoring Group'
Remove the Statistics/Data entry from the menus

Geoff has let us know that they won't have this page ready for
launch, so should be left off.
Add small zoom control to google map.

Add small zoom control and set max-width to be none on images
in the map canvas as otherwise the controls are invisible.
Rep locator: also make the representative name link to their profile
Remove duplicate places from each person on the organisation detail page

Each person entry on an organisation detail page lists the places
that that person is associated with via currently active positions.
This wouldn't remove any redundancy, so you'd see a list like:

  "Western Cape  Western Cape  Western Cape  Western Cape"

This commit changes the behaviour so that only a unique places are
shown.  Fixes #1247.
ZA: add extra tabs and tabulate members' interests data
ZA: order search results to that speeches go from newest to oldest

Fixes #1251. Relying on the ordering of django_ct happening to be
helpful isn't robust in general, but is an easy way to get the
required behaviour for launch of South Africa.
Use the updated za_hansard with Duncan's question changes

This is so that we can start rescraping the questions on the staging
site.
