I'll re-read Android's docs for Intents and tell you.  But anyway is
the best reference.

We should be able to tell
"Sugar, start this object with the best activity you can find",
"Sugar, start this object with this specific activity",
"Sugar, start this object with the activity it was created"

Note that this is the same thing the Journal exposes in the menus
"Start", "Start with..." and "Resume".  So the code is already there.

I'm trying to prevent a change in every activity, and instead use what
we already have for the Journal:
- the datastore objects metadata
- the activities mime_types declaration
- the shell registration of available activities

I'll see if this suits to Android Intents.
