Implemented Add Hide users who where online today in theme settings

I feel like this should be an option in theme config as I feel like It's a cluster of random colours that isnt really useful at all. I dont think people if any read though them names and it just makes the site look ugly and clustered as Its a big block of text.

Im working on a CSS at the moment as well and I feel like it takes from the theme. If not removed fully I feel like afunction should be added to theme settings that allows users to turn it off.

Discuss away!
