Added logic so that MSWord 2010 and beyond uses the internal export to PDF function.

Added logic to handle errors when a document is closed.  The code will attempt to do a close 10 times.  If it fails ten times, it will document the exception and continue.
If an exception occurs when an MSWord section is being saved, a message will be displayed that will document the error.
