Accessibility: Textual alternatives for unicode symbols missing

[KreerC]

The symbols used in the poll table do not have a suitable textual label for e.g. screen reader users. This could be done via aria-label or a an accessible popover containing a localized string like "yes", "no" and "maybe" as used in the code.

I'd appreciate a fix very much as this seems like a particularly easy thing to fix in poll.rb starting in line 285.

[kellerben]

you are right, this would be an easy fix. Wouldn't it be better to add this to the title in poll.rb line 290?

[KreerC]

I'm not familiar with the code per se, but I'd be happy to review a PR that implements a fix.

Also, for clarification, this should be considered a bug and receive a fix immediately because it renders the application unusable for a significant number of people.

I added the aria-label to the input. In addition, I added the unicode symbol to the title.
Can you please review it here:

https://wave.webaim.org indicates the labels appear, though adding language used for the page would likely also be helpful for screen readers.
