Automatically show description from interface

When implementing an interface it would be nice to automatically see the description of that interface on the implementation.
This should only be shown if the implemented field does not have its own description.

This should be fairly simple when dealing with a single interface, the biggest problem is what to do when multiple interfaces has the same field with different descriptions. I would suggest as the first implementation of this to simply do nothing in that case or to take the first interface and use that.
