Added another recipe for removing trailing slashes

This one is using a `before_request` hook to strip the trailing slash from `request.environ['PATH_INFO']`. I prefer it to the WSGI middleware method because it leaves the API of the app intact. For example, in the `StripPathMiddleware` snippet, you can't later add a route to `myapp` because you'll get the following error: `AttributeError: 'StripPathMiddleware' object has no attribute 'route'`.
