Captcha Math question needs to be more accessible

With this still being a problem in the 2.x branch I'm going to update the issue appropriately, create an issue fork, and reroll adriancruz's patch from #2 for the latest 2.x release.

Also updating this to a major bug due to the fact the module as written will not pass accessibility tests.

I can update the issue fork to add a span around the subset of the label containing the equation in order to satisfy the failed test but wanted to get maintainer feedback first.

Re-rolled this patch for the 2.x branch

I can confirm that we just had this issue reported to us during a mandatory accessibility audit ;-)

Thanks for the patch!

As a side note, considering this makes the captcha inaccessible, this prevents people from using forms, which may be quite important.

There I'm raising the priority of the issue.

Thanks, this also makes the captcha more accessible for bots, but I agree accessibility for humans is more important and in general this captcha type isn't highly secure.

RTBC! Let's merge this! :)

Sorry needs to be reopened to fix the test, I didn't see that -.-

@anybody, let's create a follow-up issue for that.
