Subject: [PATCH] Bugfix: tables nested in inline elements caused a
 NullPointerException. Furthermore, keep-together handling was not appropriate
 when a table is nested in an inline (fixes a ClassCastException). Finally,
 TableContentPosition did not indicate that it generates area which made them
 be ignored by the InlineLM.
