"Node Reference" webform field

I have created a proof-of-concept module to add a nodereference field to webform.

It works like this:
- Add a noderef field
- (optional) Choose a view on which to filter nodes
- The webform allows the user to select a node on the frontend
- The nid of the node is stored on the backend

If anyone is interested in this functionality, I would appreciate feedback on how you would use it.
I need it for a somewhat simple feature in which users fill out a form once for each of a particular node type they own.

Maintainers: please let me know if this would be better in contrib, and I will contrib it.
