Changed ALU3dGridFaceInfo to handle new ReferenceElements -> got rid of GridImp template parameter so that the physical dependencies could be reduced

Instead of specifying all of them for all class using IndexSet, those
class now have the index set type as a template parameters.

Renamed cube in ReferenceCubeContainer to cube_, otherwise I have a name clash with GeometryType cube; did some indentation as well

  with the default compiler and the flags extracted from the different
  mpicc-scripts. If it fails a warning is emitted and MPI deactivated

  fixes bug #23

- added theoretical support for GCC with IBM MPI: the options (which
  are tailored toward xlc) are changed a bit. However the following
  problem remains: ./configure adapts the test programs to the
  C++ compiler it find. Thus, a test program passed to mpCC fails
  because the implicitly used xlC doesn't understand the line meant
  for g++... Maybe this (and a whole lot of other problems) just
  vanish if xlc 7.0 is used so I'll do nothing about it
