create_function deprecated in PHP 7.2

Line 33 of capsman-enhanced.php needs changing from this:

	add_action('admin_notices', create_function('', 'echo \'<div id="message" class="error fade" style="color: black">' . $message . '</div>\';'));

to this:

	add_action( 'admin_notices', function() {
		echo '<div id="message" class="error fade" style="color: black">' . $message . '</div>';
	} );

Thanks for the plugin!
