Reimplement the Materials tab (#609)

* Implement Materials Tab

* Optimize Materials Tab

Materials are no longer reloaded before each frame in preview

* Remove comment

* Clean up block list

* Fix memory leak

* Code improvements from reviews

* Add blocks to the MaterialStore after the provider is registered.

* Make the material properties non-global so that they reset automatically when creating/loading a new scene.

* Fix default material properties being reset when starting the renderer.
