0.13.2: Add skipRepeats

• Add skipRepeats and skipRepeatsWith as new preferred names for distinct and distinctBy.
  • The names distinct and distinctBy are now deprecated.
• Improve handling of EventEmitter subscriptions in fromEvent.
• Optimize fromArray
• Fix for debounce dropping the last event when a stream ended early (e.g. via until).
  • If, when the stream is about to end, there is a pending debounced event, that event will be propagated just before end. The event and end will have the same timestamp.
