Also update the Blender scripts to use red/green/blue areas
instead of light and dark ones. This also allows for
three colors now.

Also update the Illustrator scripts

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

This adds a CR1632 button cell

Also fix broken attribution for utility poles

(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.
