/* Ajax batch undelete thingy, version [0.0.1]
Notes:
* It is a bit verbose, after debugging perhaps some output should be removed.
* It waits 1 second after every undelete before starting the next.
* Can be aborted by simply deleting the contents of the textarea, or leaving the page.
* Stops when it hits a blank line.
* Nonfatal errors (skip to next line):
** Bad character or malformed line
** Bad token
** Unexpected response
* Pauses in execution can be added with a blank line.
To do:
* Cache the token if two the same?
** Please note the delete token is not guaranteed to be static, but currently it always is.
