// ThrobberHandler
//
// A helper class that handles animating the throbber when it's alive. It starts
// automatically when you init it. To get it to stop, call |stopThrobber|. Calling
// |release| is not enough because the timer used to animate the images holds a strong
// ref back to the handler so it won't go away unless you break that cycle manually with
// |stopThrobber|.
//
// This class must be separate from BrowserWindowController else the
// same thing will happen there and the timer will cause it to stay alive and continue
// loading the webpage even though the window has gone away.
