Add the variables we need for the BDF-2 time stepping scheme. Remove the code that dealt with inflow boundary conditions for the temperature field -- it didn't yield a contribution so far because the velocity was always tangential to the boundary, but we also can't enforce this sort of boundary condition any more because we now have diffusion and so we need Dirichlet or Neumann b.c. all around.

Use a Q(degree) element for the temperature as well. This allows us to get rid of all the face terms in computing the right hand side of the temperature equation. On the other hand, in its current (unstabilized) version, the scheme is not stable for the transport equation, so we need to add a minimal amount of diffusion and ensure that the time step is small enough. The former restriction will be lifted once we get to proper nonlinear stabilization schemes.
