Place SVG title box on interactive
add imageMapping to interactive, use simpler instructionBox2.svg

[#40314483]

instructionBox2.svg is an exampler of a much simpler and smaller
SVG image (about 2800 bytes compared to 36K for instructionBox.svg.

I also added an imageMapping section to the Interactive

Made immune system interactive draft

This interactive requires the ability to have an image next to the interactive for selecting the antibody shape. (Could still use some other controller, but students need to see image of what they are selecting.), and the ability to click on atoms to change their charge.
Change default color of atom tracing to purple.

It was hard to see given previous default color.
