Remove references to the Stripe gem

Rather than figure out how to upgrade the Stripe gem to be compatible with future Rails, I'd rather just delete the references, since it's currently unused.

I'm not so bold as to go in and fully trash all our donation code; I just want to ensure we're not sending people down broken codepaths, and that if they reach them, the error messages are clear enough.
