This removes an old view that allowed teachers to delete their classes. However, it's not linked to from anywhere, so I'm guessing it's either not used at all or used by some chapter with some custom code (MIT?). Anywho, I don't think we should be supporting teachers deleting their classes without any oversight, so I'm removing it along with a related test and javascript. It was also the only view that used the "Teacher/Classes" permission, so I've removed that.
