Data classes for event wrappers

[octa-one]

What do you think about converting "event wrapper" classes to data classes? (TextChangeEvent, ScrollEvent, EditorActionEvent, etc)

I see at least two improvements:

• distinctUntilChanged will work correctly with overloaded equals
• ability to use destructuring declaration in collect lambdas, for example:

  
  // w/o data class
  textView.textChangeEvents().collect {
  doSmth(it.view, it.text)
  }

// with data class textView.textChangeEvents().collect { (view, text, , , _) -> doSmth(view, text) }

I agree it's a good idea and thanks for the destructuring example.

This change will change the ABI although I'm not too concerned since converting to a data class should be binary compatible change.

Great, thanks for the quick response!

This change is now available in 1.0.0-beta02.
