Fixes bug that node icon doesn't appear on forum list on XenForo 1.2. If you still receive this error after upgrading to XenForo 1.2, re-upgrade this add-on using the latest XML file after upgrading XenForo.
Fixes incompatibility with the upgrade feature of Add-on Install & Upgrade by Chris Deeming. Also, now automatically adds the Resource Manager URL for this add-on if you have the above add-on installed, regardless of the install method you use, so it can be easily upgraded in future.
