/* 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?
