Notification page setup

Initialize the notification page.
             		                            
  init: ->
    log.trace()

Populate the notification. 

Afterwards, reset ext to avoid affecting other copy requests. If the
user has disabled the notifications option this should still be called
for safety.

Set a timer to close the notification after a specified period of time,
if the user enabled the corresponding option; otherwise it should stay
open until it is closed manually by the user.
             		                            
    duration = store.get 'notifications.duration'
    setTimeout (-> close()), duration if duration > 0
             		           
                               
                            
                                
               
Initialize notification when the DOM is ready.
             		                            
utils.ready this, -> notification.init()
