You can safely merge 'update-object-icons' into 'master'.

With this PR, I do no guarantee the exhaustivity of the icons generation, I only updated the icons existing in the objects.json file.
I think this is already a good step to be merged.

I checked a few monthes ago the list was exhaustive.

[fabienrohrer]

Great. I just fear we introduced new PROTOs meanwhile. I'm checking right now.

I have checked all the images (only big ones, I assume the icons are the same) and the script is working perfectly, almost all the images are way better than the previous one, just a few ones are problematic.

Wrong background removal:

Thank you, I'm fixing this.

[fabienrohrer]

Finally, I will try also to ensure the exhaustivity here. There are only few things to do.
