Editing product attributes

Hello again and happy new year,
I was searching for an user friendly way to edit product attributes in tryton. I know that now we have import and export of product attributes in tryton. Thanks for that.

But I think there is no way to update them by import nor by having a list view to update many of them.
So I wrote a (quick and dirty :slight_smile: ) module to illustrate my idea of a module that can handle this faster.

You can download it here in a real early state:

I look forward to your comments. Collaborators welcome!
