    Fixed some of the EmpathyAccountWidget's control button behaviour.
    
    - When creating an IRC account, we are now making sure that the control
      buttons have the correct state.
    - When creating an account, the "Cancel" button is always sensitive.
    - Fixed a style error in EmpathyAccountsDialog.
