Updated whitelisted function

[therampagerado]

The original script has an update.

Part of it is more extensive whitelisted function.

If the repo is updated to 1.1.0 version I can push PR.

private static function whitelisted($ua) { return preg_match("/(a6-indexer|adsbot-google|ahrefsbot|aolbuild|apis-google|baidu|bingbot|bingpreview|butterfly|chrome|cloudflare|duckduckgo|embedly|facebookexternalhit|facebot|googlebot|google\spage\sspeed|ia_archiver|linkedinbot|mediapartners-google|msnbot|netcraftsurvey|outbrain|pinterest|quora|rogerbot|showyoubot|slackbot|slurp|sogou|teoma|tweetmemebot|twitterbot|uptimerobot|urlresolver|vkshare|w3c_validator|wordpress|wp\srocket|yandex)/i", (string)$ua); }
