Breaking menu plugins

Eighteen Tags are breaking menu plugins (like Ubermenu) because of the way you handle the menu. You should fix this bug.

The problem is in the function logo_in_nav where you are parsing everything out with PHP’s SimpleXML and then re-rendering it. Looks like you are making some bad assumptions as to what the $items object is going to look like.

BTW: SimpleXMLElement is throwing lots of warnings…
