Added in a more dynamic method for checking whether to use dblib or
sqlsrv drivers for a mssql pdo connection. This is to make local mac
devs work well with windows prod machines.

Fixed issue with options ordering when merging the default and user values into one array.

simple conditional added to look for dsn type. if set and is dblib,
syntax for PDO connection adjusted slightly to allow for mac connection
to mssql server (utilizing freetds)
