[Roger Tawa OOO till Jul 10th, 2013/12/18 20:49:35]

Instead of using GaiaAuthFetcher::StartCookieForOAuthCodeExchange() we should
use OAuth2TokenFecther like chromeos.  I'm OK with doing this in a follow up CL
since this one is just about refactoring the inline webui.

[guohui, 2013/12/18 20:51:47]

yup, will do it in a followup CL. Thanks!
