Title: minify SVG

Used [Leanify](https://github.com/JayXon/Leanify), removed about 20% from taking out comments, whitespace, etc. Even after gzip there is savings.
Not sure if using Inkscape's internal minification or some npm script is better or worse, but installing & drag/drop folder on the Leanify.exe was faster than installing & running anything else.
Original files had no trailing newline, so I also left it out.
before: 2.65 MB
after: 2.14 MB

Suggestion before release: Add a version number inside the SVG (comment). Not sure if the version should reflect the project version, image version, or both.
