We have the new Bu::CryptoHash base class and Bu::Md5 is here and ready
to rock. sha1 is still only a shell, I dunno if/when I'm going to implement that one. So far Bu::Md5 is 100% compatible with md5sum in all tests performed so far, in fact the test program's output is compatible with md5sum in every way (and it's so cute and little too!) Oh, minor update for stdstream and the formatter, they can handle more handy types now.
