Collect products to project

I would be nice to be able to load products from a library outside the project and at any point have the option to move those product inside the project.

* I think this would make ex. environment creation a lot faster and creative since the artists can pull in whatever from the global library and not have to worry about it not being archived correctly.

* The project would be less bloated since the artist does not need to fill it with stuff that is not yet approved by client. When the client approves the artist can go in and collect everything so it is secure inside the project and will work for archiving.

Maybe the “scene inventory/manager” could be used for this. (Also of course the already existing “push to project” function comes to mind for possible code re-usage)
