* Adjust old macro test to only use existing macros
* Depracate the header containing the macros (they should be replaced soon)

Clues when changing to new property system
* NEW_PROP_TAG is now a definition and can only be there once just like NEW_TYPE_TAG
  - if you're not using macros you can simply use forward declarations of properties whereever needed
  - for the most properties in dumux the definition is in the header common/properties.hh which can just be included
* The order of precedence in INHERITS_FROM is reverse than in the previous implementation
  - if the macro is used the order is flipped
  - if you replace the macro you also have to flip the order manually

* makes calls to NEW_PROP_TAG unique which will be required by the new property system

Kudos to Clang's -Wself-assign-field.

This fixes a delete-non-virtual-dtor warning from Clang.

The output only includes those default parameters which are set in dumux/common/parameters.hh. This change is intended to make this clearer to the reader of the output.

Remove warnings Wfloat-equal from dumux.
