Icons and styling for the project list

[klesun]

• Add icons to "Our popular projects": (use rendering: pixelated css - for nice scaling without soap)
• Add riddle-needle to the list with icon:
• Make the text look more like links: with more specific color (blue for example), with the hover, color change if visited and stuff. Cuz now they don't look like they are clickable at all.

• Please, add deep-assoc for vscode to the list: https://marketplace.visualstudio.com/items?itemName=klesun.deep-assoc-completion-vscode
