Enhancement: Web Interface Project Avatar URL

Hi, when using the web interface, it would be great to point at a file to be used as the project avatar.

Most of the time, the project avatar is the logo used by upstream on their repo or website, so it's available online. Alternatively, it's sometimes part of the git repo assets, which means, it's available online.

Would be great to optionally paste in a link along with the "Homepage" URL, to use as a default avatar (png, jpg, svg).
