[Dune] CMake is default build system

[Christoph Grüninger]

Dear Dune users,
I am happy to announce that we switched our default build 
system today.
Instead of autotool, CMake is now the default.

* Pass --no-cmake to dunecontrol to force the use of 
autotools.
* If no build directory is given make files, libraries and 
executables
   are in <module-dir>/build-cmake/ .
* Our CMake-related documentation can be found in the Dune 
user wiki:
   http://users.dune-project.org/projects/main-wiki/wiki/Using_cmake_to_build_your_DUNE_project
* A quick guide for the switch:
   http://users.dune-project.org/projects/main-wiki/wiki/Switching_to_CMake

Please help improving Dune by testing the new build system. 
Report bugs,
report success stories, and improve the documentation in the 
wiki!

Our plan is to keep autotools for the Dune 2.4 release and 
drop it for
Dune 3.0. Once we dropped autotools support, we are able to 
make major
changes as we don't have to consider autotools compatibility 
anymore.

I wish happy and colorful outputs,
Christoph
