#391 Done Lathe animations (#774)

* Draft PR, do not merge

* Lathe now uses animations. Timing is still wrong, code is very wet, repetitions and unused layers are there.

* Removed (unneeded?) PowerDeviceVisualizer from the lathe
Refactored & Renamed code and variables
Renamed animation names

* WIP protolathe animation

* Working protolathe animation.
I still don't like the solution though.
