[trello.com/c/iGILackD] many chat updates

[vovameister]

1. return scrolling to center using buttons and chat entering besides scroll to "new messages" separator
2. update hightlight animation, hope I also fix that sometimes its not working or removing to early
3. add short vibro while highliting
4. remove reading messages while autoscrolling (scroll to item, not scroll to bottom)
5. also remove button animation while autoscrolling
6. put position restore back so it should be earlier to not reproduce chicken animation
7. return animate = true as it was before for autoscrolling

Consider my comments, I think it becomes more complex and comples, lets make it easier!

Consider moving some of the viewModels variables to the new state

Also, I don't like approach to combine dialog and vibro, instead - use vibro directly if needs

[Lainaaa]

Also consider moving state to the viewModel

Cause it is me
