Add contributor to an item

[ImBadAtUsername]

After creating an item, nobody can modify said item.
If you want others to interact and add information on the item, you should be able to add new contributor the same way you can add contributor with viewpoint.

This could help with working with other people, which is not possible if multiple people are working on same item.
