        """Sets default so we can return whatever we want instead of index_html.

        This method is complex, and interacts with mechanisms such as
        IBrowserDefault (implemented in CMFDynamicViewFTI), LinguaPlone and
        various mechanisms for setting the default page.

        The method returns a tuple (obj, [path]) where path is a path to
        a template or other object to be acquired and displayed on the object.
        The path is determined as follows:

        0. If we're c oming from WebDAV, make sure we don't return a contained
            object "default page" ever
        1. If there is an index_html attribute (either a contained object or
            an explicit attribute) on the object, return that as the
            "default page". Note that this may be used by things like
            File and Image to return the contents of the file, for example,
            not just content-space objects created by the user.
        2. If the object implements IBrowserDefault, query this for the
            default page.
        3. If the object has a property default_page set and this gives a list
            of, or single, object id, and that object is is found in the
            folder or is the name of a skin template, return that id
        4. If the property default_page is set in site_properties and that
            property contains a list of ids of which one id is found in the
            folder, return that id
        5. If the object implements IBrowserDefault, try to get the selected
            layout.
        6. If the type has a 'folderlisting' action and no default page is
            set, use this action. This permits folders to have the default
            'view' action be 'string:${object_url}/' and hence default to
            a default page when clicking the 'view' tab, whilst allowing the
            fallback action to be specified TTW in portal_types (this action
            is typically hidden)
        7. If nothing else is found, fall back on the object's 'view' action.
        8. If this is not found, raise an AttributeError
