Magic match links

We now have intelligent links to what a reader might actually be looking for.

__Before:__ We sent readers the stats page for that match ([🐵](http://www.theguardian.com/football/match/3713194))

__After__:
* Is there a match report? Yes? Send you there.
* Is there a minute by minute? Yes? Send you there.
* Is there a Match preview and we haven't started yet? Yes? Send you there.
* No? Nothing? To the stats with you.

Details of that algorithm [are here](https://github.com/guardian/frontend/compare/magic-match-links?expand=1#diff-1290a98b5c1618b098443751b7e1f36dR108)
