	* XmlMapping.cs:
	* XmlAttributes.cs:
	* XmlSerializer.cs:
	* XmlTypeMapping.cs:
	* XmlAttributeOverrides.cs:
	* XmlSerializationWriter.cs:
	* XmlSerializationReader.cs:
	* XmlSerializerNamespaces.cs:
	* XmlSerializationGeneratedCode.cs: Added a partially stubbed out version of
	System.Xml.Serialization.dll, required for the Silverlight test suite to
	compile. A real implementation based on the same classes in System.Xml should
	eventually be done.
