The order by stuff previously only allowed specifying a particular field.
We should also be able to sort based on arbitrary expressions, and such
expressions will require the ability to bind arguments using the "?" syntax.
This changes provides a Java abstraction for the order by, and improves
the handling of selection arguments that need to bind to "?" so that both
the selection (i.e. WHERE clause) and the ORDER BY clause can provide
arguments as required.
