Added convenience method for viewing Query SQL without params.

This is the old Query.as_sql() method revived: it's like Query.__str__,
but the parameters aren't substituted into the placeholders. Thus, it's
a more accurate representation of the SQL the (default) backend will
see. Entirely internal.
