        Returns a list of action instances for a particular publish.
        This method is called each time a user clicks a publish somewhere in
        the UI.
        The data returned from this hook will be used to populate the actions
        menu for a publish.

        The mapping between Publish types and actions are kept in a different
        place (in the configuration) so at the point when this hook is called,
        the loader app has already established *which* actions are appropriate
        for this object.

        The hook should return at least one action for each item passed in via
        the actions parameter.

        This method needs to return detailed data for those actions, in the
        form of a list of dictionaries, each with name, params, caption and
        description keys.

        Because you are operating on a particular publish, you may tailor the
        output  (caption, tooltip etc) to contain custom information suitable
        for this publish.

        The ui_area parameter is a string and indicates where the publish is to
        be shown.
        - If it will be shown in the main browsing area, "main" is passed.
        - If it will be shown in the details area, "details" is passed.
        - If it will be shown in the history area, "history" is passed.

        Please note that it is perfectly possible to create more than one
        action "instance" for an action! You can for example do scene
        introspection - if the action passed in is "character_attachment"
        you may for example scan the scene, figure out all the nodes
        where this object can be attached and return a list of action
        instances:
        "attach to left hand", "attach to right hand" etc. In this case,
        when more than one object is returned for an action, use the params
        key to pass additional data into the run_action hook.

                                publish fields.
