[Plugin: URL Shortener] Bug with api username, api key, and service

I was having some trouble getting your plugin to recognize my bitly api username and key until I saw that there are a few typos in the od_get_shortlink.php preventing me from using my custom shortener.

On lines 9-13:

if (!$key && in_array($service, $this->authkey)){
		//$key = $options['apiuser_'.$service]; //wrong var
		$key = $options['apikey_'.$service];

	}
    if (!$user && in_array($service, $this->authuser)){
		//$user = $options['apikey_'.$services]; //wrong var & mispelled
		$user = $options['apiuser_'.$service];

Once I made the above modifications, it works great! Thanks for your tremendously useful plugin and hopefully, this will help others.
