Update babylon.sceneSerializer.ts

[dad72]

added collisionsEnabled and workerCollisions for serialization

[dad72]

There is a problem with this PR ? Why does it not confirm with others that have been? I make mistakes on one of its two line?
serializationObject.collisionsEnabled = scene.collisionsEnabled;
serializationObject.workerCollisions = scene.workerCollisions;

Raanan is the collision master, I think it's up to him to validate your PR. For me it seems ok (only two lines), but maybe there are some edge effects.
Just wait his feedback :)

Hi, sorry, I just waved to wait with it until I finish the scene loader as well. Merging won't matter, as it's not read yet.
I'll merge now and hopefully commit my changes in a few hours
