add the general framework for specifying auxiliary equations.

this does not disrupt the block nature of the linearized matrix
(i.e. Dune::BCRSMatrix is still used), but if the number of auxiliary
equations is smaller than that of the "main" discretization, the
superfluous equations are padded. if the number of additional
equations are larger than that of the equation, additional DOFs are
added.
