/**
* TODO: Under consideration for future rewrite: Function 'validate_username_conflict()' - Handles the conflict between validate_username
* in WP & phpBB. This is only really a problem in integrated pages when naughty WordPress plugins pull in
* registration.php.
*
* These functions should NOT collide in usage -- only in namespace. If user integration is turned on, we don't need
* WP's validate_username.
*
* Furthermore, if phpbb_validate_username is defined, then we know we most likely need to use the phpBB version.
*
* We unfortunately cannot control their usage -- phpbb expects 2 arguments, whereas WordPress only expects one.
* Therefore here we just try to avoid namespace errors.
* If they are actually invoked while renamed, the result is undefined and things could spontaneously ignite.
*
* @param string $wpValidUser the validated WP username
* @param string $username the original WP username
* @return string hopefully something nice
