Title: Wrap the default SOAPAction header in quotes.

I don't know much about soap... but I've been using your excellent library as a client working against glassfish/metro. It works great except that the glassfish log is spammed with something in the lines of "Received non-conformant unquoted header SOAPAction". I had a quick look in the specs and it seems SOAPAction should always be quoted.
