title: Jquery Validator - check input against a list of accepted values
body: <p>I would normally just do this with a drop down list but the client has requested that it be a text input...</p>
  
  <p>Basically, I'd like to use Jquery validator to check that a user has entered 1 of 50 valid US state abbreviations into a text input box.  If not, they'll get an error.  I can't seem to find a function that does this.  Any help is greatly appreciated!</p>
