Add option to disable RequestRefererService in development
Add option to disable RequestRefererService in development

This feature is very obtrusive in local development. Visiting URLs
directly is a must if you're causing interruptions and exceptions in
development, and logging in every single time wastes quite a bit time.

This is purposely over protective in that you must opt-in with the
environment variable (it's not disabled by default) _and_ be in the
development environment, to keep as much parity with production behavior
as possible and avoid any unfortunate confusion.
