[dune-pdelab] Minimum compiler support for building the PDELab

[Christian Engwer]

OK, the problem is the range base for, which was added in g++-4.6. I
found the following locations:

rgrep 'for *([^)]*[^:]:[^:][^)]*)' .
./dune/pdelab/backend/dense/matrix.hh:150:          for (auto& v : y)
./dune/pdelab/backend/dense/matrix.hh:161:          for (auto& v : y)
./dune/pdelab/gridfunctionspace/subspacelocalfunctionspace.hh:64:          for (auto& di : this->_dof_index_storage)

Ciao
Christian
