fix for performance bug #117864. implement SetQuery() on these derived classes and make it

so SetQuery() will reparse the url.  we need this because we call SetQuery()
after calling SetSpec() when quoting.  reparsing the url will set some internal state
that we use for the optimization of only quoting the body part of message,
instead of the whole message (attachments and all!)
