Internal: Add Team Images

I'm adding the team images to the repo, I'm copying them from citrusbyte.com and putting them in a folder in `/images`. I believe this is better than linking to the existing images because this will allow us to have guest posts as well (if we want.) It will also allow us to manage cb.com and bits.cb.com images separately (so we can decide if we want to leave up an article someone wrote, even if they aren't on cb.com)
