[Dune] Using a dune project create with v2.1 with the trunk

[Martin Nolte]

Actually, for compatibility with DUNE 2.1 you should use

#if DUNE_VERSION_NEWER_REV(DUNE_GRID,2,2,0)
   // new code
#else
   // old code
#endif

The DUNE_VERSION_NEWER macro contained an extra unused template argument for 
the revision, which is now gone.

Best,

Martin
