WIP: Updating the animation page.
This is an attempt at slowly updating the introduction to animation page, as per T10344.
- Introduce beginning animators to the idea of an animation pipeline.
Point people at all the separate components.
- Timeline docker
- Animation docker
- Onion skin docker
- Animation curves
- Am I missing something?
Update the walkcycle tutorial.
- For this I would really like to be able to have the animation cycles in, but that's probably gonna take a while...
