1. Add NS_CATEGORY to sightable namespaces list

done.

2. Create flag "rollback" with rollback permission

"rollbacker" group created and made addable by sysops.

3. Create "autoeditor" group with following permissions: autopatrolother,

autoreview, autoconfirmed.

I'm not sure I understand this one...

3. Create "autoeditor" group with following permissions: autopatrolother,

autoreview, autoconfirmed.

I'm not sure I understand this one...

$wgGroupPermissions['autoeditor']['autopatrolother'] = true;
$wgGroupPermissions['autoeditor']['autoreview'] = true;
$wgGroupPermissions['autoeditor']['autoconfirmed'] = true;
$wgAddGroups['sysop'][] = 'autoeditor';
$wgRemoveGroups['sysop'][] = 'autoeditor';

That's necessary for users who doesn't want to review anything but are trusted to have their edits automatically reviewed.

Oh, and set $wgGroupPermissions['autoconfirmed']['autopatrolother'] = false; (it was really unexpected behaviour, we supposed to use it to check images license, but with that config it has no sense)

Created group 'autoeditor'
Sysops can now add or remove in group 'autoeditor'.

I forgot to let sysop remove people from the group 'autoeditor'. Noticed
