Integrate with https://selfh.st/icons/ or dashboard-icons

[maelp]

What problem will this feature address?

Would be nice if the apps in the projects can have an icon for easy spotting, could be using the same as the template when it applies, or we could integrate https://selfh.st/icons/ or https://dashboardicons.com/ to find icons for custom projects

Describe the solution you'd like

Just add an optional icon to the projects
