Subject: [PATCH] Test case for space resolution in the footnote area.
 Currently disabled as the individual footnotes don't form a continuous
 element list where space resolution could be performed. Bugfix in
 PageSequenceLayoutManager: LMs are now informed about space resolution
 results and the spaces in the element lists don't cause an NPE anymore.
 AreaAdditionUtil: the layout manager parameter is now optional so it can be
 used for footnotes.
