  Be more careful about matching overloaded methods with operations.
  Now if we find a method which works, but only by using conversion,
  we continue scanning to try and find a better match.  This seems to
  clear up the overloaded WSDL generation problems that James Black
  was seeing, and since we only need to do it once, the performance hit
  won't be very noticeable.
