Log message

Change top-window calculation to not follow the opener trail, and checkin
Mac binaries with this change.

Note that this change will affect the URL that is returned to the devmode UI
in the case where a GWT app opens a new window containing a different GWT app.
Previously they would have been collapsed as two modules under the same URL,
but now they will be separate top-level URLs.  The reason for this change is
that we have run into too many issues with Selenium and other unusual ways
apps get opened, and getting it nailed down solidly will take more time than
we have.
