[Dune] dune-grid r4244.

[Robert Kloefkorn]

Hi Oli, hi dune,

the purpose of this patch is to revise the code of the DGF parser in 
order to compile this code into the grid lib to speed up compilation 
time of user code. Also dimension != dimensionworld is currently not 
running which is also changed by Martin and needed for one of our projects.

Furthermore, things like the grid type should not be in one file that 
cannot by expanded easily.

Of course, Martin is acting on behalf of the Freiburg group and to sum 
up, everything that is working now, should work after this change, but 
there should be some useful improvements.

Any suggestions?

Regards,

Robert
