Samuel Attard 795447f61a Implement dialog (alert/confirm) blocking as a user switch after the first dialog
* This is to enable more browser-like behavior so that users who run third-party code
  will not be DOS'ed with alerts and confirms.  This is already handled like this
  in most major browsers so this will greatly help these developers
