* lib/soap/baseData.rb: Introduce SOAPType as the common ancestor of

SOAPBasetype and SOAPCompoundtype.

* lib/soap/generator.rb, lib/soap/element.rb, lib/soap/encodingstyle/*:
  Encoding methods signature change.  Pass SOAPGenerator as a parameter.

* lib/soap/mapping/*, test/soap/marshal/test_marshal.rb: Refactoring for better
  marshalling/unmarshalling support.  Now I think SOAP marshaller supports all
  kind of object graph which is supported by Ruby's original marshaller.  Of
  course there could be bugs as always.  Find it.  :-)

* lib/soap/rpc/standaloneServer.rb: Set severity threshould to INFO.  DEBUG is
  too noisy.

* lib/xsd/datatypes.rb: DateTime#of is obsoleted.  Use DateTime#offset.

* test/wsdl/emptycomplextype.wsdl, test/xsd/xmlschema.xml: Avoid useless
  warning.
