/* Ajax batch delete thingy, version [0.1.1b]
Originally from: http://en.wikipedia.org/wiki/User:Splarka/ajaxbatchdelete.js

Notes:
* It is a bit verbose, after debugging perhaps some output should be removed.
* It waits 1 second after every delete 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.
