Add favicons to tab groups

[coolynx]

Take favicon from the first page in tab group and add it as tab group icon.

Human brain is very resource consuming to read everything, so it needs something faster than that. That is why images are helping. In tab groups favicons will help human brain to identify specific group with specific icon and use it next time in a search process instead of text.

I've been using emoji for this, but it's a bit of a pain to get the emoji I want copied to paste it in the tab group name editor. When I hit the os (I'm on a mac) shortcut for the system emoji picker, the tab group dropdown disappears.

Aside from that, I also use http://johannh.me/emoji-helper/ for emoji in the browser. I'm not sure how any of this is implemented, but it'd be cool if a picker like that could be integrated into this extension somehow.
