Title: Remove cookies when user click the 'Decline' link

Users have to work with OAuth's authentication UI in two step.
1. User login with username & password
2. User authenticate the app ( Allow / Decline )

If the user make a cancel in the second step ( Click cancel after login, or click the decline link ), the interface will keep showing the second state. And, there will be no way for user to login with another account.

This patch will detect 'Decline' link clicked, remove Evernote's cookies, and redirect user back to the login UI.
