Test complex<T> for floating point T only

The standard leaves (the effect of instantiating) complex<T> for more
general T unspecified.

While we're at it, kill duplicate tests and add long double to the list.

This fixes bug flyspray/FS#1726: Now also with clang 3.7 and libstdc++ 4.9.2 on Debian 8.2, the test fvectortest can be compiled again.

GitLab readable contribution guide, license and README

Adding the `.md` extension enables rendering of the files, which is much nicer.

Also ported the contribution guide from the User Wiki.

Renamed COPYING to LICENSE.md because that is the name that GitLab looks for to display it nicely on the project starting page.

If this one is accepted, I will do the same for the other core modules.

Since commit 495f2fce USE_MPI was removed from dunecontrol and
the default configuration now defaults to use
parallelism. Unfortunately, there are downstream modules that try to
support multiple versions of DUNE. Sometimes these need to decide
whether to support parallelism before they know which version of DUNE
they are using. This is was not possible when providing
--enable-parallel as no variable gets set for DUNE>=2.4.

With this commit dunecontrol always sets
CMAKE_DISABLE_FIND_PACKAGE_MPI to an appropriate value. Thus if
dunecontrol is used then one can check in one's own module whether the
variable is set explicitly to false and conclude that one is using
>=2.4 and wants parallelism. Otherwise one can check USE_MPI to detect
which behaviour is needed for 2.3.

E.g. like this:
<code>
option (USE_MPI "Use Message Passing Interface for parallel computing" OFF)

if( NOT CMAKE_DISABLE_FIND_PACKAGE_MPI STREQUAL ""
    AND NOT CMAKE_DISABLE_FIND_PACKAGE_MPI)
  set(USE_MPI ON)
endif()

if (NOT USE_MPI)
      set (CMAKE_DISABLE_FIND_PACKAGE_MPI TRUE)
 set (CMAKE_DISABLE_FIND_PACKAGE_MPI TRUE)
endif (NOT USE_MPI)
</code>

Of course without dunecontrol and using the defaults one will still
configure DUNE as parallel, but one's own module as sequential.

Actually, having these files lying around does not hurt us.
In addition there are downstream modules that especially create
these for compatibility reasons with autotools. For these
reconfiguring a module using dunecontrol currently aborts with an error

Therefore this commit resorts to just issuing a warning and proceeding
with the compilation instead of aborting with an error.

This lists all commits marked tagged as bugfix or release
that where explicitly not cherry-picked. Possible reasons for this:

* commits from a branch that was also merged to the release
* commits from a branch where the merge was cherry-picked
* bugfixes for code new to master
* commits that where picked but are not recognized as such

It's more CMake style.

Some downstream modules like pdelab and dumux already abandoned the
current bahaviour of building tests on make test. The testing infrastructure
does throw them error messages during make test though. This commi introduces
the switch DUNE_DISABLE_TEST_MAGIC which may be set by downstream modules
to disable the magic. To see how to switch a downstream module, see:
