Bug report: CKFinder 1.3.1: undefined variable: rulesMasks

(This bug report previously at: http://dev.fckeditor.net/ticket/3080 but apparently that site is for (F)CKEditor only.)

in addACLEntry in AccessControlConfig.php, $rulesMasks is undefined.

If display_errors is on, this results in an error being spat out to the XML response, resulting in invalid XML, so this is not merely a hypothetical problem.

If I supply $config['AccessControl'] as

$config['AccessControl'] = array
(
    0 => array
        (
            'role' => '*',
            'resourceType' => '*',
            'folder' => '/travel',
            'folderView' => 1,
            'folderCreate' => 1,
            'folderRename' => 0,
            'folderDelete' => 0,
            'fileView' => 1,
            'fileUpload' => 1,
            'fileRename' => 1,
            'fileDelete' => 1,
        ),

    1 => array
        (
            'role' => '*',
            'resourceType' => '*',
            'folder' => '/travel',
            'folderView' => 1,
            'folderCreate' => 1,
            'folderRename' => 1,
            'folderDelete' => 1,
            'fileView' => 1,
            'fileUpload' => 1,
            'fileRename' => 1,
            'fileDelete' => 1,
        ),


);

The following dialog comes up in IE or Chrome (firefox also presumably gets the same thing but just doesn't give the dialog) :

<?xml version="1.0" encoding="utf-8"?><br />
<b>Notice</b>:  Undefined variable: rulesMasks in <b>/path/to/ckfinder_1.3.1/core/connector/php/php5/Core/AccessControlConfig.php</b> on line <b>122</b><br />
<br />
<b>Notice</b>:  Undefined variable: rulesMasks in <b>/path/to/ckfinder_1.3.1/core/connector/php/php5/Core/AccessControlConfig.php</b> on line <b>123</b><br />
<Connector><Error number="0" /><ConnectorInfo enabled="true" s="" c="" thumbsEnabled="true" thumbsUrl="/_thumbnails/" thumbsDirectAccess="false" /><ResourceTypes /></Connector>

I know there is a repeated value for folder but I don't think that a crash is an appropriate response if the upstream ACL generator doesn't filter that.
