Add AdvancingComponent & animate flag to advance()

@luigi-rosso I pulled the AdvancingComponent stuff from the scroll branch into this, so I could build on top of it.

This PR addresses a couple of things we discussed around Layout animation:
- Added an animate param to advance which tells the advancing component whether to animate or not. This allowed the addition of a toggle for layout animation because it can be annoying to have the animation running while editing.
- Also prevent animation at runtime startup by interrupting it if ComponentDirt is filthy. This also prevents startup animation whenever a nested artboard is regenerated in editor.
