[feature] Support for alternative app icons like Arcticons

[spacefrogg]

Please describe the problem to be solved

Icons do, indeed, help with quickly navigating the search list. I cannot stand the missing cohesion between the default icons, though. So, I have currently disabled them again. Support for icon sets like Arcticons would be a quality-of-life improvement.

Thanks for the suggestion!
I agree that support for icon packs would be quite nice!
On the other hand, this seems to be a lot of work, so I think I'll deal with issues related to functionality (especially #12, #44, #45) first

For future reference:
Arcticons doesn't have a guide for how to implement support for it, they only provide an email address https://docs.arcticons.com/work-with-arcticons/launcher-developers

However some of the supported launchers are open source https://docs.arcticons.com/faq/supported-launchers
