feat #1261 Classic Test Runner branding

Related to attester/attester#56

I coined the term "Classic Test Runner" to differentiate it from Attester to have less confusion (because people keep talking "Attester" about both of them).

This PR just adds a banner with that name so that it's obvious (I hope) this is independent entity from Attester.

Should someone have better name or better CSS, scream :)
