public function SelectQuery_sqlsrv::orderRandom in Drupal driver for SQL Server and SQL Azure 7.2

Same name and namespace in other branches

1. 7.3 sqlsrv/select.inc \SelectQuery_sqlsrv::orderRandom()
2. 7 sqlsrv/select.inc \SelectQuery_sqlsrv::orderRandom()

Override of SelectQuery::orderRandom() for SQL Server.

It seems that sorting by RAND() doesn't actually work, this is a less then elegant workaround.
