Subject: [PATCH] Add filter to the attribute name label <td>

Motivations:
- other table fields are fully customizable thanks to the 'print_attribute_radio' function.
- overriding the override of the plugin is not a stable and satisfactory solution.

Potential use cases:
- add a button to the right of the name to open a size guide.
- enable a change in markup for the label itself (say you want to add js-classes to change the label on the fly depending on user interactions).
- others I did not think about.

Tested and works.
