Moots: generate panel SVG

[cosinekitty]

Moots was my first Sapphire module, and I had not yet created Python code for generating SVG files back then. More recent modules have panels that are 100% code-generated. This gives me a synergy over time of sharing a common look and feel while minimizing how much time I spend working on new panels (I can re-use code).

Issues #45 and #49 will be more tedious to resolve than one might think because of the lack of SVG scripting support in Moots.

Therefore, I'm considering starting over from scratch and generating the Moots panel completely from code. I would add a new function to make_sapphire_svg.py. Then I can go back and resolve #45 and #49 much faster.

I could just copy-n-paste the existing SVG into Python code as a generator, then add/modify stuff as needed.
