label without for can be false positive about html_codesniffer

Hi Dominic,

In the WCAG 2.0 techniques document, the method of implicitly associating labels with a form element by wrapping the LABEL element around the element was actually considered a failure, but this was changed in the March 2014 edition.

See the March 2014 version of F68 vs. September 2013 version). Note two things:

• In the latter version, the wrapping with label version was considered a failure (Failure Example 2).
• In the new version, it's now considered a legitimate method of associating a label with a form control (Procedure, 2(b)).

So I agree that this needs to be allowed.

I'm going to close this off as I'm going to merge it with #107, which is going to be the "master rewrite" issue for the "labels on inputs". There were other things to do with aria-labels that I have to include in there too.

Thanks for fixing this. Always nice when someone "out on the Internet" takes your report seriously. Keep up the good work!
