Added @crouchingbadger to the mentor section (whoop!)

Have copied text from the first mentor block:

> Ben will provide code and mentoring for teams working with internet of things.

Maybe it looks a bit odd next to my description (especially with us both being Ben), any suggestions for better copy?

Also, @crouchingbadger, we grabbed your image from linkedin which is a bit low res.  Have you got a 430×430 version, or a different one entirely?
