Title: Small usability tweak for adding product attributes

When you add a specific product attribute, you first select the attribute name from a dropdown list, then you click "Add". Previously the select list remained the same with the same attribute selected. This makes no sense because you can't add the same attribute again.

With this small tweak, the select list gets reset to the "Custom product attribute" option, which always can be added.
