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 exe was faster than installing anything else.
Original files had no trailing newline, so I also left it out.
