v0.0.10: refactor API, internals, testing

[Gugustinette]

DONE

• Refactor the API to hide every third-party related objects as __INTERNALS__
  • physic system : hide every Rapier object
  • components : hide meshes, textures, containers,...
  • 3d camera : hide Three.js camera
• Refactor transform system
  • FTransform(which correspond to the transform property) should now be used directly to modify attached-object (component, light, camera, colliders, rigidbodies,...) transforms
  • Wrappers like initCollider or initRigidBody now are short-hand to "create then attach object"
  • Introduce FVector3d and FVector2d types for consistency
  • Everything should be reactive
• Configure and create tests
  • Configure coverage
• Add onLoaded callback feature on all FComponents
• Add autoLoop option on FScene to turn off automatic frame compute each frame
  • This is useful for test environment but will also be used in the future for creating debug features (manipulating the scene frame per frame...)
• Components and lights are now added to scene by default
  • Add addToScene option on FComponent to turn off adding components to the scene automatically
• Normalize frame and onFrame behavior on FComponent and FScene
  • onFrame takes a callback function that will be called each frame
  • frame computes the new properties for the object on a new frame
• Add FRigidBodyType enum to replace the RAPIER one
• Update documentation
