Replace calls to deprecated `DUNE_VERSION_NEWER_REV(DUNE_ISTL,2,7,1)`
by `DUNE_VERSION_GT_REV(DUNE_ISTL,2,7,0)` which also reads better than
the `GTE` version, as Dune 2.7.1 hasn't been released yet. Fix the
call to `DUNE_VERSION_GT(DUNE_ISTL,2,7)` in the solver factory
backend which would break things in case of a 2.7.1 release. Adapt
the corresponding changelog entry.

Also remove unnecessary inclusions of the header.

Rename `VtkOutputFields` to `IOFields`. Add `primaryVariableName`
functions, don't use centralized names yet. Add required template
parameters. Adapt properties correspondingly.

This patch reduces dependencies and makes usage of linear solvers more flexible, i.e. for two problems with different typetag

* Linear solvers don't need type tag anymore, in fact they don't need any template params
* the preconditioner block size is now provided for the solve method (see e.g. staggered newton controller)
* the amg has a convencience alias using a TypeTag but is "independent" through indirection via the traits

* [test][richards] Fix solver include
  (Used to compile before due to indirect include over newtoncontroller.

The Doxygen comment `//!` refers to the line after the comment. If
the comment should refer to the same line, `//!<` has to be used.

* use dumux/common/properties.hh instead of dumux/common/propertysystem.hh
