Add archiver

What does this do?

Uses scraped-page-archive to archive all pages scraped.

Why is this needed?

Elections happened recently (2016-11-20), and it's likely that the data on the official site will disappear, meaning any data we're not already picking up will be lost. Archiving it now gives us the chance to go back and re-scrape later even if it disappears.

Relevant Issue(s):

everypolitician/everypolitician-data#20544

Checklists:

Scraper page

• scraper is on Morph.io under the "everypolitician-scrapers" group https://morph.io/everypolitician-scrapers/san_marino_council
  actually: currently it isn't, it's in tmtmtmtm at the moment
• scraper's GitHub "Website" link points at morph.io page https://github.com/tmtmtmtm/san_marino_council
  note: not everypolitician-scrapers yet
• scraper is set to auto-run https://morph.io/everypolitician-scrapers/san_marino_council/settings
• scraper has webhook set (usually only set on Wikidata person-data scrapers) Not needed
• scraper is configured for archiving (unless source doesn't require that) @tmtmtmtm please add GitHub auth ENV settings for https://morph.io/tmtmtmtm/san_marino_council thx!

Scraper is not under EP-scrapers account on morph.

Add archiving

• we are using at least version 0.5 of scraped-page-archive-gem
• scraper uses scraped-page-archive gem directly or via a suitable strategy
• MORPH_SCRAPER_CACHE_GITHUB_REPO_URL is configured
• pages are being archived in new branch of correct scraper repo https://github.com/everypolitician-scrapers/san_marino_council/tree/scraped-pages-archive
  actually not all of them yet (yes they are! 18-Nov-16 DW)

The scraper was run locally to archive the current version of the page.

After temperamental timeouts, the scraper finally ran to completion so archived all visited pages just now -- looks like it's captured all of them pre-election, phew!

I've rebased this over master, but can't merge yet as the scraper is currently failing.
