This commit adds a `useUnless` helper method which can be used as a middleware for express. It receives an express-middleware and an array of paths. When a request matches one of the given paths, this middleware does nothing. Otherwise the given middleware is called. For the express-session middleware this helper middleware is used to avoid session creation on purely status routes. See #1446 Signed-off-by: Erik Michelson <github@erik.michelson.eu>
