towards implementing MBLayout not as dense bits but an explicit set of sequences (which will be needed for sequence-to-sequence, and woiuld also make fix DelayedValueBase for m_timeStep > 1):

flags can now ONLY be set through AddSequence() or AddGap(), i.e. in full sequences (MBLayout::Set() is now private, and SetWithourOr() and Mask() are commented out);
HTKMLFReader and LUSequenceReader have been modified to follow the new method (also heavily commented that code);
BatchSequenceReader (LMSequenceReader project) not so much: It did not set end or gap flags, so it could not be fixed (and likely did not work before this change, either). Instead, it now throws at those places;
EvalReader did not maintain the needed state, so the fix will have incorrectness for DelayedValueNodes with m_timeStep > 1;
RecurrentNode currently disabled for m_timeStep > 1, as that will be fixed  very differently once this is complete;
DecimateMinibatch() temporarily disabled. We need a new method in MBLayout to support this
