Removed some personnel

Per conversation with Justin, I have removed some of our alumni personnel and updated Albert Rafetseder's title. I also checked with Nick about current Lind personnel and removed two individuals from that list.

I will be adding two new people to the Lind team next week, but I think these removals can be processed now.
