Added anchor to comments

[niklabh]

Closes: #776

• anchors on each comment
• an additional #end anchor on the last one
• link directly to comments in the "new comment posted" emails
• share comments with others
• go straight to the end of a thread by just adding #end to the end of a thread's URL
• add a link "Go to bottom" to the top of the thread which will take a user to #end, i.e. the last comment.

One other thing worth considering maybe would be to have the comment timestamp as a link for the comment (similar to Github and others). Though this might make the CreationLabel a bit too convoluted.

I haven't tested it yet, but there are many placed where we don't follow React best practices. It'd be great if we can adapt these getElementById to useRef instead.

Nice thanks it's cool now.
I think this "back to top" is totally invisible, and that the "go to bottom" is also not placed where it probably should (all the action button next to it relate to the post, this is unrelated).

but overall it's bringing a lot of value so let's merge. I'll create an issue for the rest. (edit: #842)

I tried to add a circular button but couldn't find a good place for it

I'm not convinced we need a go to bottom tbh now that we have direct links. Back to top yes, and then it can be a button just like you had, but at the bottom. That would surely work.
