Add music and sounds

[QuinnBast]

The current app provides no music. Create a music controller that plays music throughout the application and attach the sound effects that cake created to the relevnt game objects!

Describe the solution you'd like
When changing a scene in unity the sound should continue playing and once a sound is done the music should shuffle to another random track.

Additional context
In addition to this, we will probably want to start creating the settings page. This would include a "master volume" and "SFX" slider so that players can control the application volume.

Edit: Reopening because the sond FX settings are not created yet.
