Fix memory leaks to MavenPomEditor

When opening and closing a MavenPomEditor, two references will stay:
- the wst ConfigurableContentOutlinePage of the source page keeps one
- the IDocument keeps a reference to the IDocumentListener inner class

The former is actually a bug in wst since the
ConfigurableContentOutlinePage is leaked, but that is nowhere near
important as the MavenPomEditor which can easily have a cumulated size
of 100MB (due to its reference to MavenProject).
