    build: Add license and required meson version
    
    The project function allows a License parameter which enhances the
    project information. The project's AGPL3 license has been aded.
    
    The function also allows a required meson version parameter. The
    gnome module was added in the 0.37.0 version, so that version has
    been added as the minimum required meson version.
