* use new method to update the auto loader cache
* use new interface
* use new interface to trigger a cache flush
* update the console upgrade menu
* update the missing implements syntax
* add the clear_cache to the flush cache button
* use boolean setting as true boolean
* Update settings class to use the php filter_var function for boolean
Using the built-in filter type for boolean seems like a better option as they are faster, already hardened, and more widely tested.
I found this better method used originally by Mark J. Crane in 2022 in the content.php page so I included it here.

* add the apcu caching ability for performance
When the PHP extension APCu is loaded, the settings class and the auto_loader will cache their results across requests in RAM. For more information about the APCu extension visit the PHP page: https://www.php.net/apcu
* use global instead of default terminology
