Make Journal active at startup. #2159

Browse Source 
Also distinguish between "active" in the sense of "the user is actually
using this activity" and "active" in the sense of "the activity would
be active *if* the user switched to Activity view". It's the latter sense,
now called "pending" that the Journal is in at startup. Pending is also
used for the next-up activity when you quit the current active activity.
