Version 2 of this patch, it changes
- fixed the memory leak of RenderObject::NodeInfo objects
- if 'cachedInnerNode' has a 'URLElement' and a 'nodeAtPoint' call to this
  node does return 'inside' but doesn't include a 'URLElement', copy it
  from 'cachedInnerNode'. Seems to happen on some mailing list archives.
