Improved SEO fundamentals test and more

A number of updates this week:

SEO fundamentals test

We're revised all checkpoints to make this test more useful and less pedantic about minor issues:

• Recommended title length is now 60 characters (was 55), now a potential issue, not a confirmed one
• Missing heading text is now a potential issue, not a confirmed one
• Longest acceptable anchor text is now 200 characters (was 60), now a potential issue, not a confirmed one
• Long meta descriptions are now a potential issue, not a confirmed one

We've also revised the user interface to make issues easier to understand, including better visuals on the left-hand sidebar, and clearer descriptions.

We also now display the languages a website was tested in at the top of the Spelling test.

Broken links

The broken links test now displays explanations for any broken links it finds:
