added .ToMd5Hash()
* moved extensions for MemberInfo into their own static class - please keep it so that all extension methods for Type X find themselfs in a class XExtensions
* made some nested types in the test assembly first-class types
* made sure that the meta-assertions do not fuzz about types in the test assembly not being public or some such if those types are not test classes
* no console output in the metaassertions tests, instead outputting the name of the failure causing class in the asserts - makes life easier under NCrunch
