	* AllTests.cs: Renabled most tests after commenting all code causing a
	cyclic dependency (corlib->System.Xml->corlib). Some tests will fail
	until commented code is replaced.
	* SymmetricAlgorithm.cs: New (189) generated test cases for all default
	algorithm implementation, all cipher modes, all padding modes, all key
	sizes, all block sizes, feedback...
	* PKCS1MaskGenerationMethodTest.cs: Commented vector test. Added new
	tests to check for various exceptions
