Return User when Connection ready resolves

[lukeatkins]

Can we please update the Connection class to return the User when the ready function resolves?
This way we can use it to logout from the device.
I don't see another way to logout with the API.
If we don't logout and try to login again, the device throws an error saying someone is already logged in.

Connection.js, line 72 onwards:

    _this.initializeCsrfTokensAndSession().then(function () {
        // Login code
        if (username) {
            // Username is specified, we need to login
            var user = new User_1.User(_this, username, password);
            user.login(true).then(function () {
                resolve(user); //Return the user that has logged in.
            }).catch(reject);
        }
        else {
            resolve();
        }
    }).catch(reject);
});
