/* Ajax mass user-rollback, version [0.0.1b]
Originally from: http://en.wikipedia.org/wiki/User:Splarka/ajaxmassrollback.js
Notes:
* Oh god this is ugly code. Haha.
* This does not revert moves but thinks it does. Not sure how to skip them either. BE AWARE.
* This only goes back 7 (configurable) days by default, but should work with any number of contribs in that timeframe.
Operation:
* Gets user's contribs (query-continues until reaching the time limit).
** For each contrib that is (top) and not (new) it leaves a checkbox (and info/links).
* After selecting which to rollback via checkboxes, it iterates over these checkboxes.
** For each revid, it gets the rollback token, title, and user.
*** Upon getting the token, it attempts rollback.
**** If successful, checkbox is unchecked and next is selected (after 1 second delay).
To do:
* Delete link for pages created by user? Maybe.
* Rewrite for efficiency when generator=usercontribs becomes implemented! Oh yah.
* Markbot optional?
* Reason field?
