 * Animate any element with specific animation. Animation is done by CSS and runs multiple times.

 * Animation is started when element is appended to the DOM or new (not same) animation is added
 * to already displayed element. Animation runs on hidden elements too and is not paused/stopped
 * when element is set as hidden.
 *
 * @param widget Widget to apply animation to.
 * @param animation Custom CSS class name used as animation.
 * @param count Number of animation repeats. 0 disables animation, any negative value set repeats to infinite.
 * @param duration Animation duration in ms. 0 disables animation, any negative value keeps default of original animation.
 * @param delay Delay before starting the animation loop in ms. Value <= 0 means no delay.
 * @param <T> Any object extending UIObject class (typically Widget).
 * @return Animation's CSS class name, which can be removed to stop animation.
