* Get the flags for a field, currently supports "not_null", "primary_key",
* "auto_increment" (mssql identity), "timestamp" (mssql timestamp),
* "unique_key" (mssql unique index, unique check or primary_key) and
* "multiple_key" (multikey index)
* mssql timestamp is NOT similar to the mysql timestamp so this is maybe
* not useful at all - is the behaviour of mysql_field_flags that primary
* keys are alway unique? is the interpretation of multiple_key correct?
* @param string The table name
* @param string The field
