The splash is now an application that should be started and forked from.
Once started, it will listen for messages on a ZeroMQ socket reporting
progress.
The current protocol is extremely simple, reporting (optional) label,
and reporting a progress amount.
Additionally, it responds to a string commant ("quit") to quit as
needed.
