xdg_shell / native wayland Apps result in the same shell-icon

[nikolaisen-hhpv]

Thanks for the great app! I actually like the concept a lot.

Issue
Right now all xdg_shell windows which is basically every native Wayland application results in the same icon, no matter if it is chromium, foot terminal or Dota 2 (Wayland native).

Wanted Behavior
The values being scraped should not depend just on the window type. Maybe the title or some other attribute might be a better way to determine the default attached icon.
