step-9: Modify the refinement cycle and linear solver.

1. The different refinement strategy seems to work better with the higher degree
   finite element.
2. Bicgstab has trouble converging (and does not converge in the max norm) for
   finer grids. GMRES is more consistent for this problem.
3. I added some extra console output to show the residual (which does not always
   converge with Bicgstab) and the number of DoFs.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
