Add a cause enum to UserBalanceUpdateEvent (#2824)

Browse Source 
Basically, I just needed this for one of my plugins; otherwise, this could be useful for people using this event who want to see where the user's balance is being updated from.

---

* Add UserBalanceUpdateEvent.Cause
* Add special cause enum
* Add API Cause
