[#30830] Detect Google Search App (GSA) NOT as Safari

Google Search App on IPad or IPhone (others?) throws "Can't Identify Browser Version" because is identfiied as Safari.

So, 'function identifyBrowserVersion()' in 'browser.php' fails, because it tries to identify the Browser-Version via a RegEx that uses "Version" as identifier but not "GSA".
