This fix ensures, that for example -I'dune-common' is only added once to
the DUNE_CPPFLAGS.

- add --enable-dunedevel which switches a define DUNE_DEVEL_MODE that
  in turn can be used to activate more output (will e.g. be used for
  exception output format)
- --with-dune works with both the directory above and the real
  dune-dir... if the directory is called "dune". Well, otherwise the
  includes won't work anyway :)

- added two types of library-check:
  a) normal search for lib in default-path (for a global installation
     some time in the future)
  b) a check for a signs of a compiled lib in a local
     Dune-installation if "localdune" is enabled. This is by no chance
     a strict check but what we want for local development

problematic, but aclocal now correctly shows the names in verbose-mode

- fixed a bug that would have added a useless -I parameter if dune was
  installed in a default location (where it should live in the near
  future)
