Create vector images for the book/site

@BradenLawrence do you want to help with these? Each can be individually PR'd if you'd like. The final result should be a web-friendly SVG so we can easily edit in the future. They should go in public/images folder.

~I'll ask Ember Observer about whether they can lend some spaceships~ Ember Observer's only asset is the logo, so we should make a thing

Sure thing! I took a stab at the first button image in your concept sketches. You had mentioned doing a sketchbook style, so did a few tests following that theme. Here are a few different directions we could go:

1. Simplest look, I'm thinking we could apply some kind of texture to this to make it feel more hand drawn.
2. A more vector look with enough complexity that it wouldn't need a texture.
3. A 'sticker' style inspired by the white outlined Ember logo.
4. A variation on the above with a peeled corner effect.

Any thoughts on these? I could do a few more variations on one or two of them.
