make a SoundPlayer interface so we can mock it in the tests

this requires an annoying amount of scaffolding:
1. implement gst and mock classes to implement the SoundPlayer interface
2. modify notifier to take a SoundPlayer argument in its ctor
3. modify service to take a Notifier argument in its ctor instead of instantiating it on its own
4. change main to update the startup steps for player/notifier/service
