Link to interactiveqa.com is bust (well, doesn't include the http)

The last Extra's tag has two items of concern. Mostly it's the broken link.

- Link to InteractiveQA to thank them for this module.
- Thank you for using the QA Checklist. If you need professional QA for your site, contact us at interactiveqa.com.

However, why not give a shout out to others who are pushing this module forward? There's also setting up a Flattr profile so that we can try to fund additional development & ensure that this fits with the best practices.

Finally, I think disabling this module may well be something that belongs here. Once you've got through the QA you want to see a report and then stop loading the code.
