app icon: Initial app icon

[daudix]

Adds app icon

(BTW I noticed that app id is slightly wrong, it should have Halftone starting with capital letter and use io.github instead of com.github)

Thank you very much! Also, thanks for notifying me about that app ID

Hmm, I kinda messed up with fixing merge conflicts, as it now shows in PR also changes from my commit, but it should be okay nonetheless.

[daudix]

no problem, I'm still experimenting with the icon, if needed I can open new PR

[tfuxu]

@daudix-UFO Do you want to change something in design, or can I merge?

[daudix]

I think it's fine :D

[tfuxu]

Great :) LGTM then!
