[WIP] Per-object effects

Currently you need to use layers to add effects to objects, but I think it would be a lot easier and better in general if you could apply effects to specific objects using events instead of having to move the object to a layer. It could also allow for more customization, if for example you wanted to give objects a glow based on one of their objects variables.

The first steps for add effects on object has started some days ago.
This is in progress :wink:
Here if you want follow the main thread (for developpers).

Oh wow! Thanks for the info, I will check it out.
