What we have now is show_object_in_journal, which activities can use
to ask Rainbow to show a journal object. The activity creates a
journal object, and then calls that resulting in Journal displaying
that object. You can then resume / instantiate it.

This is how Chat opens URLs in Browse. I imagine that it could be used
to create a journal object corresponding to the activity type you want
to open. However, where a specific mime type can be opened with
multiple activities, you could choose to resume any one of them. So
this doesn't guarantee a specific activity will be launched.
