Minor MS SQL improvements

Browse Source 
Support 'sql_ssl' option for MS SQL - set Encryption=required and
Encrypt=yes in ODBC connection string to require SSL using default
FreeTDS driver and Microsoft ODBC Driver for SQL Server repectively.

Allow setting full ODBC connection string in 'sql_server' for MS SQL,
allowing custom connection configuration beyond what is possible with
just 'sql_odbc_driver' option.
