[Dune] EntityPointer constructor from Entity and method compactify.

Hello Dune,

as promised in Berlin I implemented a way to construct entity pointers 
from entities. Given an entity one can construct an entity pointer by 

EntityPointer p ( entity );

Furthermore, the entity pointer now has a method named 'compactity()'
which releases all temporarily used memory of the entity pointer in 
order to keep memory allocation small for a list of entity pointers.

Although the method is implemented for all Grids in dune-grid
this feature is at the moment only supported by ALUGrid and SGrid.
All other implementations contain an empty method.
