* feat(tools): scene component injection & export
- ambient light, shadowmap resolution, bloom intensity, ambient occlusion are now directly settable from scene components that are injected automatically in the scene
- relaxed requirements for changes(aka when to export gltf) for main scenes,
so that render , background etc changes also trigger a save
- added scene components examples
- added additional proxies & handling for camera & lights
- in relevant cases, made sure that entity specific components are not overridden by scene components
- added option to toggle scene level exports of params/ components
- ambient colour/ intensity is now also set as background/clear colour
- updated docs
