PartialList / FilterList shoud trow an exception if
you try to add a non JDOM object to it.

I'm sure it will be interesting to add to the contrib.

PartialList / FilterList is used because because one needed:

- A partial/filtered live list when doing Element.getChildren() on
   a Element with mixed content. getChildren() return a list with
   only the Elements in the content list.
- A list implementation that knows to disallow adding non JDOM objects
   to itself
- A list that knows to set the parent reference of the Added JDOM
   objects to the Element that contanis it, and to clear the parent
   when content is removed.

Anyone know when FilterList will be introdused?
