[Bartłomiej Piotrowski <bpiotrowski src gnome org>]

commit 61b91881d77a9bb4c679bd68db37d6f5d6e784c4

    Allow uploading larger presentations (#1977)
    
    * Allow uploading larger presentations
    
    This patch allows uploading presentations up to 30MB instead of the
    default 1MB. This should prevent users from getting an 401 reply from
    Nginx in most cases.
    
    * Update greenlight.nginx
