"socketChange" event for the OWOT client #230
Description
The OWOT client currently provides no event to tell when the socket's URL has changed, making scripts have to rely on harder, inefficient, and less maintainable methods to detect events like world warps. Adding an event that fires whenever the WebSocket's URL has changed would make detection of world changes much easier.
Additionally, it may also be helpful to have 2 events: 1 where the socket's URL has just changed, and another one when the world model state has loaded.
