Archive file icons with type names

[Jiří Wolker]

Hi all,

I suggest adding some text that describes file format to mimetype icons 
for archive files with size 64.

Few examples: 
https://invent.kde.org/frameworks/breeze-icons/uploads/e552bcdd2d9f7fd23a8f266e489f02c8/icons.svg

For example, when I have icon of plain tar file, there would be “tar” 
written in the bottom-center part of icon. This part is currently only 
filled with solid color.

I think that such modification would be useful for the user (the icon 
gives the user enough information about the format) and it would also 
utilize the empty solid-color area in icons that looks, at least for me, 
“too empty”. Currently, the only difference between the all archive 
icons is color and shape of the “zipper”.

Regards.
