Also update the Illustrator scripts

Also adds an Illustrator script that automatically
handles all of the tracing

Drawing an SVGImageElement to a canvas goes haywire. This checks for
that behavior and warns about it, and turns off the fine-grained

Also fix broken attribution for utility poles

That was a Blender thing. Also updates the process-model
script so that it runs some stuff in parallel, which might
make it slightly less agonizingly slow.

(just a credit card for now, though). This also introduces some fixes
to the process-model script, allowing for it to compensate for the
extra height introduced by the line art. blender-model.py is adjusted
to allow for this, and makeModel() now checks for the bottom/extra
values produced by the process.

This would cause problems in Firefox

Auto prey capacity was getting set to false, rather than 'off'.
It was also showing up when it shouldn't have. The blender script
ignores spaces in the view list now. makeModel wasn't including
mass correcetly.
