- new db adapter for MS SQL Server
- changed the getUniqueID(conn, tableName) to return the last generated by the db unique ID
instead of generating unique ID first by the appl and then supplied to the insert,
because SQL Server doesn't have capabilities
unique ID to be generated on the client and then supplied to the insert.
