Audio queues on certain actions

**Is your feature request related to a problem? Please describe.**
Sometimes, when doing an action like posting, it can appear like it didn't work though it did, as sometimes, new posts can take some time to show up on the timeline.

**Describe the solution you'd like**
It would be nice to have audio queues on posting, reposting, new posts, etc. This would be a good indication to the user as "yes, that action worked" (or not).

**Describe alternatives you've considered**
Using another client (though Phanpy is cooler).

**Additional context**
I used to have a Misskey instance which has those and are a good way to know when an action is done.

Also related to #292 though this one is broader.
