Promises

[callumacrae]

I have the following code:

    user.save()
        .then(function () {
            req.login(user, function (err) {
                if (err) {
                    next(err);
                } else {
                    auth.login(req, res);
                }
            });
        })
        .error(function (err) {
            winston.err(err);
        });

It would be nicer as:

    user.save()
        .then(function () {
            return req.login(user);
        })
        .then(function () {
            auth.login(req, res);
        })
        .error(function (err) {
            winston.err(err);
        });

If I added support for promises to passport, would you merge it?

Would this only impact req.login?

I think so; do any other functions accept callbacks?

No, that should be it. I'm not opposed. If you need to pull in a promise library, I'd prefer promise since that seems the most lightweight.

Closing. See comment for rationale.

See issue #536 for adding promise support now that a lot of time has passed since this issue was created.
