Init check
Include <config.h> to fix build on GCC 4.8

GCC 4.8 provides 'nullptr' in C++11 mode.  That capability is
detected at configuration time and stored in <config.h> and we need
it when targeting Dune 2.2.1 to avoid diagnostics of the form

  [...]/dune/common/nullptr.hh:27:1:
  error: expected ‘;’ after class definition
   } nullptr = {};              // and whose name is nullptr
    ^

  [...]/dune/common/nullptr.hh:27:1:
  error: qualifiers can only be specified for objects and functions
  [...]/dune/common/nullptr.hh:27:3:
  error: expected unqualified-id before ‘nullptr’
   } nullptr = {};              // and whose name is nullptr

PVT properties: allow them to be temperature dependent

Note that this patch does not introduce any real temperature
dependence but only changes the APIs for the viscosity and for the
density related methods. Note that I also don't like the fact that
this requires so many changes to so many files, but with the current
design of the property classes I cannot see a way to avoid this...
