Exposing Timeline's mainObject

[Andres Almiray <aalmiray@yahoo.com>]

Hi Kirill,

I've come across a use case where having read-only access to the Timeline's mainObject property would be a good thing to have.
Integrating Remi's triggers yields the following code for the animated button sample

  button("One", id: "button", foreground: Color.BLUE)
  timeline(button, duration: 2500) {
      mouseTrigger(button, event: 'enter', autoReverse: true)
      interpolatedProperty("foreground", from: Color.BLUE, to: Color.RED)
  }

While it is short and concise you can appreciate that the mouseTrigger() node must have a repeated entry for the button variable.
If access to Timeline.mainObject is possible then the trigger can read it from the parent Timeline, resulting in a DRY approach

  button("One", id: "button", foreground: Color.BLUE)
  timeline(button, duration: 2500) {
      mouseTrigger(event: 'enter', autoReverse: true)
      interpolatedProperty("foreground", from: Color.BLUE, to: Color.RED)
  }

What do you think? Worth having for 1.3?

Cheers,
Andres
