/* 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.
