The admin-init hook only fires on admin screens. The correct hook to use for registering post types is init.
So change:
add_action( 'admin_init', 'smoelenboek' );
… to …
add_action( 'init', 'smoelenboek' );
… and flush your rewrite rules once (save permalink settings in admin) and all should be well.
