User Notes (#707)

* Notes implementation.
Bug: Client does not save note locally after uploading to server. Client does save after reloading page. Is this due to the response being sent by PUT?

* I don't know why the client doesn't do optimistic UI updates with this, or any updates at all without reloading the page

* Added USER_NOTE_UPDATE event, thanks @TheRealGeoDash2019 !
