* include dumux/common/properties.hh instead of
  dumux/common/basicproperties.hh and dumux/common/propertysystem.hh

Everything in our .hh files is defined within the namespace `Dumux`.
There were numerous occurrences of `Dumux::` qualifiers that were
unnecessary. Remove those occurrences. Necessary qualifications
remain, such as `typedef Dumux::H2O<Scalar> H2O;`.

* Make current density publicly available
* Use standard grid creator
* Implement reaction source term for box and cell-centered

fixes make headercheck for various files

* Remove trailing whitespace and tabs
* Move electrochemistry output to the test problem (not related to 2pnc in general)
* Make electrochemistry have static members
* Use naming conventions for indices in the model
* Try to make the model work with cellcentered too (No cell-centered test available so far)
* Make electrochemistry input parameters part of a group "ElectroChemistry"
* Make the electrochemistry model a named enum (ElectroChemistryModel)for readability

- BuildBot failed for commit -r 15292. The possible reason was the usage of static const int as template parameter for electrochemistry. (checked with M.Schneider)
- Unused variable removed from h2on2o2fluidsystem.hh 
- Unnecessary headers removed from test_box2pnc.cc

- The required binary coefficients are added.
- Electrochemistry equations added for both isothermal and non-isothermal cases (Non-isothermal are not used till now).
- pc-s relation for hydrophobic material  added
- h2ON2o2 fluid system added
- fuelcell test case is the new test problem for 2pnc model.

Moreover, some updated related to 2pncmin model are included
