Add environment variables for MSSQL configuration and JTDS configuration. Add examples of mssql-db and jtds-db configuration for testing. Add test clauses for generated keys for SQL Server (work-in-progress - usable keys are not returned yet). Add exclusions for metadata test because SQL Server actually returns something useful(!).
…ia Microsoft's own driver and the jTDS driver.
Add commented out MS SQL Server Driver 3.0 for testing. If you download the MS driver and install sqljdbc4.jar as sqljdbc4/sqljdbc4 3.0 then you can uncomment this dependency and run tests against mssql using the Microsoft driver.
