More automatic voice channel management

[gwillen]

Proposed:

• When a voice channel has people in it, have the bot automatically make it public (after a short delay.)
• When a voice channel no longer has people in it, have the bot automatically make it private (after a short delay.)
• When a puzzle is solved, delete the voice channel (once it's empty, after an additional short delay.)
• Have some way to make the voice channel come back if we turn out to need it again.
• When someone joins the voice channel for a puzzle, automatically join them to the puzzle so they get the text channel as well.

Having all occupied voice channels public means they're going to clutter up the sidebar, even more than text channels because of listing the people in them. And it will make it harder to find the voice channel for the puzzle I'm working on (I often misclicked on wrong voice channels when I was subscribed to multiple puzzles at once).

I like the idea of somehow knowing where people are in voice channels, because I do miss being able to have puzzle solving background noise, even if I'm working on something else. But I think this would not be the most usable solution.

Also, if all occupied voice channels were public, I don't think I'd want to automatically be added to the text channel just because I happened to click the voice channel.

I agree with Sparky on this one. But I do understand the desire to want to know at a single glance what's actively being worked on. I don't think the current hb!who command really solves this. I can't think of a really good way to have something permanently visible on discord, but maybe an extra pseudo-round at the top of herring containing all puzzles with people in voice?

I don't know what the metric currently used by the activity tracker on Herring is, but possibly if there were something like that per-puzzle that showed me which ones had people in voice channels would be good?

I tried to talk about this in #52 but the whole way we expose presence is basically nonsense. The dark "people" icon in Herring represents people who have typed in text chat in the last two hours. The little sparkline also represents activity in text chat and also activity on spreadsheets (I think). #52 addresses adding voice chat membership to these, but it has a different model so it was harder than it looked and I didn't do it.
