SET defaults

Updated the initail sql call to set default settings flags to match
those generated by ADO.NET/SQL Server Management Studio.

These are considered "sane" & "least suprise" defaults (for example,
linked server queries fail without a couple settings here, etc).

This also addresses issue #59
Revert change to where 'database' config is taken from for connection.

fixes #80
Merge pull request #83 from kppullin/set-defaults
