[Seaside] WATree

Reason that the expanded nodes are not remembered could be:

- the WATree is instantiated on every rendering pass in
#renderContentOn:, this should be only done one in #initalize.

- the nodes do not properly implement #=, in my image file-directory
uses #== for comparison which does not work with WATree.

Hope this helps,
