Clean out repo
Created by: Huluti
- Remove "old_logo" folder.
- Rename images with better names.
- Optimize all png and svg.
I would like to go even further and wonder if it is really necessary to keep the PNGs of all colors. If someone needs a logo with a particular color, it still has the ability to use the svg file and change the color. Let's KISS.
If you have other suggestions or ideas to improve structure of this repo, just comment in this PR.
Moreover, why do we have two repos for logos ? https://github.com/manjaro/artwork-logo and https://github.com/manjaro/artworks/tree/master/logo
