Added crayon syntax highlighter support

I have implemented the crayon syntax highlighter support in AnsPress editor, now you can easily add codes to question and answer.

Make sure to read this How to enable code button and syntax highlighter

Some examples:

public function check_recaptcha()
{
	$recaptcha = new \ReCaptcha\ReCaptcha(ap_opt('recaptcha_secret_key'));
	$resp = $recaptcha->verify($_POST['g-recaptcha-response'], $_SERVER['REMOTE_ADDR']);
	
	if ($resp->isSuccess())
		return true;

	return false;
}
