Passport v0.5.0

[jaredhanson]

This release improves Passport's internals to avoid extending the prototype of the IncomingMessage class of Node.js's core http module. Instead, the login(), logIn(), logout(), logOut(), isAuthenticated(), and isUnauthenticated() functions are added directly to each request as it passes through passport.initialize() middleware.

This releases also fixes a potential race condition in situations where passport.initialize() is used multiple times within an application with different values for the userProperty option.

For more information, see the announcement on the blog and details in the CHANGELOG.
