I'm pretty sure how to accomplish this.  If an Activity wants to open the
browser, perhaps in response to clicking a link, it should
1. Save the link as an object in the datastore.  It should have a mime
type indicating that it is a URL, like "text/uri-list".
2. Ask the Journal to display the detailed view for this new object.

That's it for the activity.
3.  The user opens the object like any other Journal object.  This
requires one click.  Alternatively, the user decides not to open the
object, or decides to do something more complicated with the object.
