/**
* Displays a sliding notification window.
*
* @param imageUrl A URL identifying the image to put in the alert.
* The OS X implemenation limits the amount of time it
* will wait for an icon to load to six seconds. After
* that time the alert will show with no icon.
* @param title The title for the alert.
* @param text The contents of the alert.
* @param textClickable If true, causes the alert text to look like a link
* and notifies the listener when user attempts to
* click the alert text.
* @param cookie A blind cookie the alert will pass back to the
* consumer during the alert listener callbacks.
* @param alertListener Used for callbacks. May be null if the caller
* doesn't care about callbacks.
* @param name The name of the notification. This is currently only
* used on Android and OS X. On Android the name is
* hashed and used as a notification ID. Notifications
* will replace previous notifications with the same name.
* @param dir Bidi override for the title. Valid values are
* "auto", "ltr" or "rtl". Only available on supported
* platforms.
* @param lang Language of title and text of the alert. Only available
* on supported platforms.
* @throws NS_ERROR_NOT_AVAILABLE If the notification cannot be displayed.
*
* The following arguments will be passed to the alertListener's observe()
* method:
* subject - null
* topic - "alertfinished" when the alert goes away
* "alertclickcallback" when the text is clicked
* "alertshow" when the alert is shown
* data - the value of the cookie parameter passed to showAlertNotification.
*
* @note Depending on current circumstances (if the user's in a fullscreen
* application, for instance), the alert might not be displayed at all.
* In that case, if an alert listener is passed in it will receive the
* "alertfinished" notification immediately.
