Mark BOOST_STATIC_ASSERT with 'CGAL_UNUSED' 

In order to fix such a warning from g++-4.8:
  warning: typedef ‘boost_static_assert_typedef_241’ locally defined but
  not used [-Wunused-local-typedefs]
then:
  - create one macro CGAL_UNUSED that is "__attribute__ ((__unused__))"
    with g++ or empty otherwise,
  - use it after BOOST_STATIC_ASSERT in the definition of
    CGAL_static_assertion.
