[dune-pdelab] Vector and Matrix backends for PETSc

[Matthias Wohlmuth]

  Hi,
the recently introduced petsc-backend added trouble vor codes using 
complex numbers because of

   typedef typename Backend::template Matrix<double> Matrix;
instead of
   typedef typename 
LFSU::Traits::FiniteElementType::Traits::LocalBasisType::Traits::RangeFieldType 
ElementType;
   typedef typename Backend::template Matrix<ElementType> Matrix;

Similar to several, other pieces of code in istl/common ....  it only 
works (and compiles!) with real numbers. Of course, this patch is not a 
systematic complex-numbers patch for the trunk, but perhaps this helps 
to be aware of this problem when adding new code.
The attached patch fixes the problems for the Accessor-Petsc class and 
similar places in the same directory.

Best,
Matthias
