Title: Update 09.1-animation.md

In order to avoid issues like #2371 I updated documentation to clarify that react.js have in in this version.
Add note about ReactTransitionGroup, that any additional, user-defined, properties will be become properties of the rendered component.
And example how to render a `

` with css class.
