Display and send votes in polls

[andybalaam]

This is the first draft of votes being sent and displayed in polls.

Later pull requests will fix some issues:

• a limit on the number of characters in questions in answers
• overlap of option text with the vote count in some screen sizes
• error messages and waiting spinners when actions are happening

@SimonBrandner we're labelling polls stuff as T-Task for now, so it doesn't appear in the release notes until it's ready to use.

Ah, sorry for misusing the label, thanks for letting me know

Actually I think it's probably me misusing the labels, but I guess not calling it a feature when it's hidden behind a labs flag is sort-of legit.

I wholeheartedly disagree with the verdict of this poll, but it's a lovely render!

I actually had to re-do the screenshot because I accidentally got the wrong answer first time.

Overall looks fine - just a few human linter things that we really should put into the lint rules.

[andybalaam]

I have completed all the requested changes, thanks.
