	* XmlTextWriter2.cs : fixed some relationship between
	  ConformanceLevel, OmitXmlDeclaration and WriteStartDocument().
	  See new tests more details.
	* XmlWriter.cs : it could reuse XmlTextWriter.ctor(TextWriter,
	  XmlWriterSettings). It also resulted in dropping several internal
	  members in XmlTextWriter.

	* XmlWriterSettingsTests.cs : added tests for relationship between
	  ConformanceLevel, OmitXmlDeclaration and WriteStartDocument().
