Fixed #291, added FF35, and updated CH39 results.

Also, this adds `<br>`s to some platform column names so that they aren't uncharacteristically wide compared to the others.

FF35 is in Aurora mode, so there may still be some latitude for it to change its support, at least compared to Beta. Since Nightly has several features that are deliberately disabled in Beta and Stable, I don't think it's too wise to ever make columns for it, no matter how exciting.
