Inteface should not have shared_ptr for Camera

[Dreikblack]

Currently camera may stay when it's not intended. Could be cases when camera component/script have interface and it will be a circular reference and they will stuck in memory when scene is cleared.

Should be weak_ptr as Interface member with GetCamera method to return shared version for internal needs.

Maybe. I will have to investigate this in detail. I suppose if the camera goes out of scope, the UI won't render anyways, so there's probably no harm in just letting it silently stop drawing.
