[io] Implement general gridcreator

Everything can be controlled by the input file: Changing

File = ./grid.dgf


File = ./grid.gmsh

or into

LowerLeft = 0 0 0
UpperRight = 1 1 1
Cells = 20 30 10

will construct a gmsh grid or a structured grid instead of the dgf grid.
The grid creator is the new standard grid creator.
To use all features dune 2.4 is required (e.g. structured grid factory)
but it dgf/gmsh works with dune 2.3. The structured grid factories can
be deprecated as soon as dune 2.4 is released.

additional feature:
- set inital refinement in Grid.Refinement  (oder options can be easily
  added, write me)
- grid specific parameter in input file, e.g.  UGGrid: Grid.ClosureType
  = None
turns off green refinement (triangles closure).
- new property GridParameterGroup sets the input file group the grid
  creator is looking in. Particularly useful for two grid simulations:

File = bla.dgf

File = blub.dgf

#define GET_RUNTIME_PARAM_FROM_GROUP(TypeTag, ParamType, GroupName, ParamName) \
::Dumux::Parameters::getRuntime<TypeTag, ParamType>(#GroupName, #ParamName)
* \ingroup Parameter
* \brief Retrieve a runtime parameter which _does not_ have a default value taken from
* the Dumux property system.
* The third argument is group name, which has to be a c-string
* This allows to use string variables as group name. The functionality of having varaibles as
* group name is no problem when directly using the Dune::ParameterTree. For consistency with the
* macro way of reading in the parameters this macro is necessary e.g. in the gridcreator to reach
* a satisfying level of generality.
* Example with a temporary c-string:
* \code
* // -> retrieves global integer value "NumberOfCellsX" which is
* // located in the parameter group "Grid"
* GET_RUNTIME_PARAM_FROM_GROUP_CSTRING(TypeTag, int, "Grid", NumberOfCellsX);
* \endcode
* Example with a string variable:
* \code
* // -> retrieves global integer value "NumberOfCellsX" which is
* // located in the parameter group "Grid"
* std::string groupName = "Grid";
* GET_RUNTIME_PARAM_FROM_GROUP_CSTRING(TypeTag, int, groupName.c_str(), NumberOfCellsX);
* \endcode
