[eog] Increase zoom level when toggling the zoom button

[Felix Riemann <friemann src gnome org>]

commit 5bf0e3581e0b79ae217722f35d17f6021cc09871
Author: Felix Riemann <friemann gnome org>
Date:   Mon May 25 19:12:23 2015 +0200

    Increase zoom level when toggling the zoom button
    
    Use the steps the zoom logic used in earlier eog versions.
    Also add a zoom level at 133% to not have the zoom jump
    to 200% when starting at 100% zoom.
