Adds the button to toggle between dark/light themes, and adds the dark theme

[dejlek]

As the title says. I have tested it locally and it works pretty well. I am not a web dev guru so I may have missed something. Please let me know what needs to be changed, added or removed. Also feel free to do any modifications by yourself if you wish.

@dejlek could you maybe tweak it a little bit to automatically conform to user's system dark/light preference please?

You can check out this ts code and html declarations from my blog if you like.

Hi @dejlek , before I take a closer look at this, could I ask if this is for the forum.dlang.org instance, or another instance? (Just want you to be aware that in case it's the former, this will not affect that instance, as it overrides the files edited in this PR.)

[dejlek]

It is for forum.dlang.org, yes. But I will also use DFeed for DDN forum (https://ddn.ovh).
I will check your link to see if I can do something there. Thanks for letting me know.

Looks like they do not overwrite the skel.htt file. So in order to do it for forum.dlang.org I will need both this PR, and another PR in dlang.org it seems...

Not sure if that's what you mean or not, but forum-template.dd is rendered to the skel.htt file used for forum.dlang.org:

@ahmetsait , nope. - I will leave that to you as you already know how to do it. So hopefully next PR will be from you.

Thanks man. I missed that! I know nothing about Nix, will need to look at that... Thanks for pointing that out.
