Fix for warning message

This plugin puts a lot of messages into the debug.log as a result of a poorly-tested function. This is the fix, to replace the function at line 42 of version 1.4.4 of google-web-fonts-manager.php. Apologies for the generic variable names; I didn’t have time to fully comprehend the purpose of the function, since my goal is just to produce code that will remove the debug spam without changing functionality at all:

protected function get_option($setting) {
        $new = $this->_options[$setting];
	    if (is_array($new)) {
            $base = get_option($setting);
	        $options = $base ? array_merge($new, $base) : $new;
	    } else {
	        $options = get_option($setting, $new);
	    }

	    return $options;
	}
