The temporary file <dune-module>-config-version.tmp!

With this patch autotools now creates the file
<dune-module>-config-version.cmake mit autotools. To facilitate this
we added the variables DUNE_MOD_{MAJOR,MINOR,REVISION} to the makefiles.

In the CMake package configuration files generated with autotools
the CMake name of the library target contained a bogus lib in front
of it. This packages fixes this. Now the library can be referenced
in CMake as dunemodule (without dashes).

Due to testing the wrong directories some variables where missing in the
package configuration files. This patch fixes this.

When unpacking the tarballs, the time stamps are preserved, but the
access time of the files might be set differently. In addition during
configure Doxyfile is always created. This resulted in some files being
newer than the doxygen-tag in the tarball and triggered building the
documentation. This patch fixes the problem for me by only checking the
modification time and excluding Doxyfile.

The cause for the problem was the introduction of cmake/modules. This caused
the find statement to always print something. This patch simply excludes
cmake/modules from the result with grep -v.

The am_DATA variable was set to EXTRA_DIST which contained
CMakeLists.txt. Therfore CMakeLists.txt was installed.
This patch fixes this by listing files to install in am_DATA
and using EXTRA_DIST only for those files that are otherwise
not distributed. Suprisingly, some files from am_DATA have to
be listed there, too.

E.g. the files in am are now installed to share/am/dune-module instead of share/am.

fix the last doxygen fix

some accidential debug statements broke the build for a clean checkout

make doxygen work in out-of-source builds:
extra magic to find the correct doxygen-tag file

don't try to install doxygen when documentation is disabled

always install doxygen files, even if we didn't generate them

The documentation is still not built and therefore not installed

This fixes #803, but leaves us with the ugly situation, that docs in the 
tar balls don't get installed, if doxygen is missing.
