- Removed dependency on cmake version 2.8.9
  Object libraries can now be created with dune_add_library(<target>
  OBJECT <sources>). It will create a GLOBAL property
  _DUNE_TARGET_OBJECTS:<target>_ that records the full path to the
  source files. Theses can later be referenced by providing
  _DUNE_TARGET_OBJECTS:<target>_ as one of the sources to dune_add_library

have been already seen by the linker. As DUNE_LIBS (e.g. dune-grid)
use symbols from other libraries already in ALL_PKG_LIBS (e.g. those of the
alugrid library), they should be appended to them.

On the other hand libtool removes duplicate libraries provided when
linking from, such that only the first occurence persits. Resulting
e.g. in libalugrid coming after libgrid.

This never caused problems because libtool added dependencies known to
it from the .la file automatically. But it does when using dune core
packages built with cmake (these lack .la files).

All tests of the core module pass (except one in virtual
refinement). Additionally dune-grid-howto build with ug and alugrid enabled.
