2.1.1 release preparations

[akarnokd]

Version 2.1.1 - June 21, 2017 (Maven)

Notable changes

The emitter API (such as FlowableEmitter, SingleEmitter, etc.) now features a new method, tryOnError that tries to emit the Throwable if the sequence is not cancelled/disposed. Unlike the regular onError, if the downstream is no longer willing to accept events, the method returns false and doesn't signal an UndeliverableException.
