[devhelp: 16/16] Call dh_book_manager_free_singleton() at the end of main()

[Sébastien Wilmet <swilmet src gnome org>]

commit 54038fe2b2edf97a42475814cab444be4ea31937
Author: Sébastien Wilmet <swilmet gnome org>
Date:   Mon May 1 18:55:26 2017 +0200

    Call dh_book_manager_free_singleton() at the end of main()
    
    The function needs to be exported by the library, because the Devhelp
    app is dynamically linked to the Devhelp library.
