19 * @brief Login box for Disobedience
21 * As of 2.1 we have only two buttons: Login and Cancel.
23 * If you hit Login then a login is attempted. If it works the window
24 * disappears and the settings are saved, otherwise they are NOT saved and the
27 * It you hit Cancel then the window disappears without saving anything.
30 * - cancel/close should be consistent with properties
