Update hibernate files to initialize timestamp

Updated the hibernate hbm.xml files to correct the following issues:
1) Timestamps had generated="insert" but hibernate was not auto-populating
	the timestamp value thus the DB was generating an exception.  Modified
	the definition of this field to cause hibernate to provide the default
	value of CURRENT_TIMESTAMP.  This impacted most of the hbm.xml files.
2) While running junit tests, the following message appeared in the log
	underneath most of the hbm.xml files:
		Recognized obsolete hibernate namespace
			http://hibernate.sourceforge.net/. Use namespace
			http://www.hibernate.org/dtd/ instead. Refer to
			Hibernate 3.6 Migration Guide!
	Updated most of the hbm.xml files, changing the namespace per the
	guide.  Note: a couple of the files were already correctly configured.
