Enhancement: Improved friend UI/visibility

[Quintium]

Lichess on a mobile browser currently offers no way to access your friend list from your home page. The desktop version has a drop down at the bottom right, which is in my opinion an unintuitive place to look for (it took me a year to even notice it) and only shows online friends.

Even if you can go to your profile and click on the "Friends" link, I feel like lichess should have a friends button on its home page since this is probably quite an important feature for a lot of users.

The mobile app tackles this problem quite well by displaying a friends icon in the top right. I suggest that a similar feature is implemented in both the mobile and desktop website: A friends icon next to the search icon, showing the number of online friends in a small orange circle, and displaying all of your friends when clicked, showing the online ones at the top.
