* Closes#1241: Add wsConnecting event
* Remove redundant tests
(The separate tests for connecting, open, and close events are handled by the one lifecycle event test which both tests that the events are called as expected and in the order expected.)
* Add event.type to detail object of wsConnecting event
(This makes the event polymorphic for this property path with the other lifecycle events – wsOpen and wsClose – which proxy the underlying socket’s event object. This means all lifecycle events can be handled by one handler – e.g., a status indication function – if desired.)
* Minor: Add missing semicolon
* Document wsConnecting event
(And fix two tiny grammar issues.)
* Add events support for WebSockets
* Stop reconnection attempts after element has been removed
* Add tests for websockets
* Hide socker wrapper behind a more strict interface to avoid breaking changes in the future
* Fix legacy websocket tests interfering with new extension tests
* Minor doc fixes
* Add `wsBinaryType` configuration option
