add spotlight comment with old name

Summary:
To make the transition from the old to the new name as smooth as possible, we want to allow people to launch the app using its old name via Spotlight.
Therefore, we set a comment on the executable with the old name. These comments are indexed by Spotlight and the app can be launched with the old name.
