While XTools is thinking, we need some visual feedback so that people don't keep clicking Submit.
This could include any or all of the following: disabling the Submit button, show a spinner, show a count of time waiting, show "please wait, this could take a minute"
Do whatever you think is relevant/helpful.
I've added a ponderator to all submit buttons. It's nothing fancy: just stops the re-clicking of the submit button, changes the text to 'Loading' followed by a counting-up minutes-and-seconds timer.
