r3653: Move Interactive login tests up with the rest of the logon tests.
(Hmm, this whole section should be broken out into a new file, I

Add new tests, particularly of the LM key for NTLMv2 responses, and
the (changed, apparently) session key for LMv2 only logins.

Next is to add SAMR modification and cross-validation.
