Add sounds to the effects

[DaemonLoki]

This could add a nice touch and a new dimension to the effects.

Could be a config option because it wouldn't always make sense. Still a lot of things to figure out here:

• how to best incorporate it in the developer experience
• where to get sounds that are free to use for our use-case
• how to handle e.g. long-running audio (loops?)

@DaemonLoki I love this one. We can check epidemic sounds for some sound effects
