`CancellableEventBus#addListener` might be confusing with the boolean parameter
The cancellable event bus has custom addListener events to handle listeners that cancel the event. There is one such method: addListener(boolean, Consumer<T>), where true causes the listener to always be cancelled. Even with documentation, I fear that this method may be confusing to those reading the code, and is an unnecessary additional parameter for what is effectively a different method call.
I think this should be replaced with something like addListernerCancelling(Consumer<T>).
Technically it's an addAlwaysCancellingListener(Consumer<T>) but I thought that was a bit verbose and would make people question why the never cancelling one isn't called addNeverCancellingListener(Consumer<T>).
The reason why never cancelling listeners have the same addListener(Consumer<T>) name and signature on both CancellableEventBus and EventBus is for cross-compatibility. For example, if you don't care about cancelling the event, your add listener code shouldn't break just because the event no longer implements the Cancellable characteristic.
