// What does it do?
// 
// * Auto-retries server join so you don't have to spam the button.
//   (close the Game Manager error popup to cancel the auto-join)
// 
// What might it do in the future?
// 
// * Remember server browser sorting preference.
// * Prevent the server browser from jumping to the top on refresh.
// * Possibly other stuff related to server browsing / joining.
// 
// Notes
// 
// * This is a work in progress.
// * This is tested only in Chrome 14.
// * It works for me.

This has been replaced with a much newer, better version.

Fantastic!
