[Suggestion][Feature] : Add polls for guests

[mariebmo]

At times it'd be nice to have a poll for people attending - like having a poll for the movie to watch at a movie-night, or a theme for the upcoming quiz.

Yes, we certainly need some sort of system for easy questions. In addition to the sort of polls you're presenting, asking for food preferences when ordering is very useful

Never mind my comment, that was more about #98

I think the primary use case here would maybe be scheduling. There are other good apps that do this (https://app.rallly.co/ is my current favourite), so I haven't prioritised it. However, I've been getting requests for this, and it would be handy to do something simple right in Shera.

Open for thoughts!
