Only inherit themes which are really needed

[alexxcons]

Hi Boston team,

now that the related xdg merge request got merged and v0.18 of the spec got released, I am starting my mission to get the "Inherits" attribute right for popular icon-themes to prevent potentially missing icons 🙂

Currently Boston has:

Inherits=Adwaita,gnome,hicolor,breeze,Arc,PiXflat

I wonder why Adwaita, gnome, breeze, Arc, and PiXflat are listed here ... is Boston lacking fd.org icons which need to be provided by these?

If there is no strong reason to keep them in the Inherits list, I would suggest dropping them.

If one/some of the other themes need to stay on the list for some reason, it makes sense to have a section in the README.md to explain packagers that the boston-icon-theme package should have a hard dependency on the other listed themes.
