Heads up: .on() no longer returns instance, breaking api

[bkw]

Just a quick heads up that somewhere between 2.1.0 and 2.2.1 the api was changed so that calls to bottleneck.on() no longer return the bottleneck instance and thus are no longer chainable.

Maybe not a biggie, but probably still worth a mention in the release notes since (for us) this was a breaking change and makes bottlenecks behavior now differ from node's events.EventEmitter.on().

Thanks for the bug report, it will be fixed in 2.2.2
