messageTray: Provide a hook for customizing banners

Browse Source 
While we want to encourage the use of regular notification banners,
some of our built-in stuff does require more or less customized content
("more" being chat notifications, a.k.a. king of custom).
Account for this use case by delegating banner creation to a method,
so either Notification or Source subclasses can overwrite it.
