Support For Categories

[sprankhub]

Thanks a lot for this nice tool!

One nice addition would be to show the same hint for categories as well (on the category edit page).

@sprankhub You are right. Please see #5 for a WIP version of that.

If I am not mistaken, #5 is a different thing. It adds support for the categories a product is assigned to, so this works on the product edit page.

What I had in mind was to have the hint on category edit pages for category attributes.
