// This goes in application.js
// Using this, the confirmation alerts on Rails 3.1 will be replaced with this behaviour:
// The link text changes to 'Sure?' for 2 seconds. If you click the button again within 2 seconds the action is performed,
// otherwise the text of the link (or button) flips back and nothing happens.
