Fixes to test files for MSSQL. Bug fix in mssql.cfc select method when using the dao.read(tablename) syntax - columns weren't being properly passed in.
* Added ability to auto-detect the db type for mysql and mssql datasources.  Now the dbtype argument is optional to the dao.cfc constructor.
* Fixed bug in for-in loop of the variables.meta in the makeTable() method. The variables.meta wasn't being converted to a CF object before the makeTable was called (only when a model CFC was instantiated against a table that didn't exist)
* Some clean up.
