Consistent game emails

Need a way to make rendering in email consistent, email clients can mess with the game rendering in unpredictable ways.

Have been experimenting with image renderings which show promise but still have issues around client resizing.

Rendering for Alhambra and cathedral is also broken in mobile Chrome:

I've actually got a feeling that's fixable using whitespace: pre instead of whitespace: pre-wrap, but then we'd need to look at manual line breaking for long text. I like the idea of using whitespace: pre though because it'd make wide games like RTTA horizontally scrollable instead of breaking it up.
