- avoid updating seek time from UI if source of seek time is studio, to avoid re-processing timeline info

- move generating animation to first thing in a frame, and notifying about timeline changes to last, to ensure that it happens before the time updates
- re-generate the animation tweens whenever you start playing or manually seek a new time in the timeline to prevent inconsistencies
