Title: Fixed JDatabaseQueryPreparable to support binding output parameters

When interacting with stored procedures that use output parameters, JDatabaseQueryPreparable would not update the original passed in parameter as expected with the values output from the stored procedure. To solve this, the value is passed by reference so that when it is bound to the query, it can be updated properly with the new value after query execution.
