• Updates for RxSwift release candidate rc-0
• change shareReplay(1) to use the new API share(replay: 1, scope: .forever)

RxSwift ShareSubject

• The Mortred release of RxSwift completely changed it's behavior. With the introduction of SubjectLifetimeScope enum. The default is to use .share(replay: 1, scope: .whileConnected) or .share(replay: 1) which means the same thing. The above mentioned behavior see that When the number of subscribers drops from 1 to 0 and connection to source sequence is disposed, subject will be cleared.
  In Action sticked to the old behavior .shareReplay(1) which is represented in the new api as follows .share(replay: 1, scope: .forever) This behavior see that after number of subscribers drops from 1 to 0 and connection to source observable sequence is disposed, this operator will continue holding a reference to the same subject. So the talking point here is that on Action.elements after source sequence terminates any new observer will always immediatelly receive replayed elements
