Deprecate order() methods on Query, ExpressionList - migrate to orderBy()

Unfortunately we have order() and orderBy() methods which do the
same thing. I have decided to deprecate the order() ones in
favour of the orderBy() methods so that ultimately we will end
up with less methods and I think orderBy() is the correct choice.

Apologies for the migration pain here.
