[AndyB] Human verification 1.3

Adds a human verification overlay to your forum.

Stops resource-hungry AI bots and automated scrapers in their tracks. By requiring a quick human verification click before the forum can be viewed, this lightweight add-on ensures your server resources are reserved for real users, not crawlers. Includes options to whitelist trusted search engine bots like Googlebot so your SEO remains unaffected.
