Add darkpopout parameter to chat embed

[nicholi]

Alternative pull request to #40 to fix #30.

Intead of adding a UI button, just pull parameter from querystring and use on rendering template.

I think dark mode is a very desirable feature, no matter how it is enabled.

This is going to be a bit rough around the edges:

• If you change the open streams via the "change streams" box, the new chats will not be dark mode.
• There's no easy way to find out about dark mode or turn it on for someone who hasn't seen this pull request.

That said, dark mode has been a massively requested feature and this seems like a fine way to get it available even if it's not particularly polished. Thanks for sending the PR and sorry for not noticing it for so long!

My temp fix for the first one is go to Right Click the light themed chat, Inspect Element>Elements>Look for

" html class="tw-root--hover js-focus-visible tw-root--theme-light" data-js-focus-visible="" lang="en-US" "

then change the "tw-root--theme-light" to "tw-root--theme-dark" and that specific light chat would go dark mode.
