    environment: Parse repeat-count and auto-reverse
    
    Those are two useful ClutterTimeline properties and
    will be needed for wiggling the search entry when
    failing the password.
    
    Add support for passing repeat-count and auto-reverse
    to ClutterActor.ease and ClutterActor.ease_property.
