SET defaults

Updated the initial sql call to set default settings flags to match those generated by ADO.NET/SQL Server Management Studio, as validated by SQL Server Profiler.

These are considered "sane" & "least suprise" defaults (for example, linked server queries fail without a couple settings here, etc).

The same effect may be forced by the `ODBC_ON` flag in `login7-payload.coffee`, however I'm unaware if this can cause other unintended side effects (again, settings can be verified in SQL Server Profiler).
