Fixed issues with the liquibase script.
	Updated the inv_stock_room_item.import_transaction_id column to batch_operation_id.
	Updated the stockroom item FK to the old transactions table to now poin to the operation table.
	Added the operation_type column to the inv_stock_operation_type table.  This is used by hibernate as a subclass discriminator.
	Fixed some typos where a few of the id columns had an extra '>' that messed up the xml.
