The method returns a boundary type for a given boundary id.
The function spaces need a parameter class which makes this mapping and the
parameter class has to be defined by the user.

GridDefault class. Default implementation is doing nothing.

Furthermore removed BoundaryType and moved to DiscreteFunctionSpace in
dune/fem/common.

BoundaryEntity implementation moved to grid.cc

Added subBoundaryId method on EntityDefault which work just the same way as
subIndex but for the method boundaryId.

Added GridName which returns name of grid for given GridIdentifier.
