Football preview. Now with BigFatScore

Previously we were including the <abbr title="Big Fat Score">`BFS`</abbr> on the liveblog only, and then the `scoreSummary` on other page types.

It is now `BFS` on all pages (preview, liveblog) and the `scoreSummary` solely on the report.

There was a little refactor in this as we were using a few factors to decide what type of page we were on (tags, `config.vars` etc). We now use `match.pageType`.

In the refactor there was some legwork removed for when you're on a stats page.
