Now really added Makefile and Makefile.am to svn::ignore for folders

multidomain and subfolder common. Obviously, "svn propset svn:ignore
FILETOIGNORE ." replaces previously added files in the ignore-list.
Either all files which should be ignored have to be listed in one
command, or software which allows to conveniently add a file to the
ignore-list like eclipse can be used. In the command line, "svn propedit
svn:ignore ." can do the job.

An alternative would be to add a file, which contains the list of
ignored files/folders with "svn propset -F fileWithListOfIgnores", but
this is not the way it is done in Dumux so far.
