Here's my second pass at the launcher patch.  This version changes
little in the actual behavior of the code, but substantially cleans up
the code itself.  I pulled all of the "pending_activity" code out,
simplifying the model a good deal, as we no longer need it with the
new Home design.  I also re-factored the flow of the launch (and
launch failed) notifications, unifying so that everything occurs first
in the model which then sends signals to the view, rather than having
the view call the model in some cases and vice versa, which led to
inconsistencies.

These changes also made the calls to notify_launch in the shell
cleaner, passing the home_activity object instead of several other
parameters, which in turn cleaned up the call stack for
setting/changing the launching activity icon.  I'm much more satisfied
here.

The main problem that remains is that the launching activity feedback
is still mostly maintained within the view.  The model remains
unchanged from before.  We need to clean this up so that a launching
activity (which doesn't yet have a window) can still be considered
active in the model, so that the view always properly reflects the
model instead of tiptoeing around it to achieve the launching feedback
effect.

Thoughts on how to best achieve this goal are welcomed, as it gets a
bit more intimate with the window management business that I'm
unfamiliar with.
