Include almost all icons needed icons to repository

[qarmin]

Some OS doesn't have currently used icons or icons looks just bad, so I think that the best is to use same set of icons.

License of https://github.com/Nitrux/luv-icon-theme is quite good but have a lot of symbolic icons, but I want to use normal icons.

Currently used icons:
