Patch that adds the 'noratelimits' right
I don't really understand why we still have $wgRateLimitsExcludedGroups = array('sysop', 'bureaucrat'); while we could as well have:
$wgGroupPermissions['sysop']['noratelimits'] = true;
$wgGroupPermissions['bureaucrat']['noratelimits'] = true;
Is there some underlying reason I'm missing here, or is it just that no one has thought of this and/or gotten around to implementing this yet?
