[Dune] Problem with compiling grid.globalIdSet()

Hi Aleksejs,

the forward declaration you are missing can be found in line 360 of 
dune/grid/common/grid.hh:

    template< class GridImp, class IndexSetImp,
                      class IndexTypeImp = unsigned int,
                      class TypesImp = std::vector< GeometryType > >
    class IndexSet;

If you are not happy with the default values just explicitly state the 
optional third and fourth template parameters.

Regards,
Christoph
