Bug 33499: Make interface URL clickable on vendor details

This patch adds markup around the vendor details interface URL so that
it is a clickable link.

To test, apply the patch and go to Acquisitions.

- Search for a vendor
- If you don't have a vendor with interfaces defined, edit one
  - Under Interfaces -> Interface details, fill out the form, including
    the URI field.
  - Add more than one interface
- Save your changes and then view the vendor details page
- In the Interfaces section the interfaces you defined should have
  clickable links.
