[Dune] Change heapsize, StructuredGridFactory, UGGrid

[Carsten Gräser]

Hi,
there are two way to solve this problem:

* With dune 2.0 you can construct a UGGrid with appropiate heap
  size and hand it to a non-standard constructor of the factory.

* If you use the trunk you can call the new static method
  UGGrid::setDefaultHeapSize(...) to set the heap size for all
  subsequently constructed UGGrids.

Best,
Carsten
