Core updates for the new color schemes.

* Update about page, there's now 8.
 * Display them four wide, not three, and ensure adequate spacing.
 * Use a dedicated nonce.
 * Push Light to the front in addition to Default.
 * Use user-profile.js on about.php. A few extra things are initialized but they are harmless.
