* Renames `objectactions` to `change_actions`
* Removes `get_object_actions` (see below)
* Adds `changelist_actions` for creating action tools in the change list view too
* Adds `get_change_actions` and `get_changelist_actions`
Breaking changes
* Deleted `get_object_actions(request, context, **kwargs)`. If you used this
before, use `get_change_actions(request, object_id, form_url)` instead. To
get at the original object, instead of `context['original']`, you can use
`self.model.get(pk=object_id)`, `self.get_object(request, object_id)`, etc.
This isn't as convenient as it used to be, but now it uses the officially
documented way to add extra context to admin views.

* Renamed `objectactions`. In your admin, instead of defining your actions in
the `objectactions` attribute, use `change_actions`.
