[jdom-interest] Missing removeContent() methods

[Elliotte Rusty Harold]

By my reckoning the Element class is missing two removeContent() methods 
it should logically have:

public boolean removeContent()

  removes all content from the element

public boolean removeContent(List list)

 removes everything in the list from the element

We do have equivalent versions of removeChildren() but these only 
operate on child elements, not all possible kinds of children.
