RollbackModification
What (summary)
Create a special group for RecentChanges patrollers which includes only the rollback tool.
Why this is important
The hope is by giving people the ability to have a tool to do RecentChanges - more people will help do it. This will assist RecentChanges patrollers - who aren't administrators with their work and give them a much-needed tool to make the job quicker.

Steps to get to DoneDone
There's instructions in http://www.mediawiki.org/wiki/Help:User_rights.
This involves adding one line to the wiki's LocalSettings.php.
Something like:
$wgGroupPermissions['patroller']['rollback'] = true;
(A new group can be defined using the same one-line directive)
Adding users to the group is through the same process used to promote administrators (Special:Userrights).
