Dan Winship 6f57f07214 [MessageTray] Clean up source-vs-notification icon handling 
A Source needs exactly one summary icon (which in the case of a
trayicon-based source won't even be just an image), but possibly many
notification icons, which may vary for successive notifications
(particularly in the case of NotificationDaemon notifications). So
differentiate these cases in the API.

//
// By default, the icon shown is created by calling
// source.createNotificationIcon(). However, you can override this
// by passing an 'icon' parameter in @params.

// Additional notification details can be added, in which case the
// notification can be expanded by moving the pointer into it. In
// expanded mode, the banner text disappears, and there can be one or
// more rows of additional content. This content is put inside a
// scrollview, so if it gets too tall, the notification will scroll
// rather than continuing to grow. In addition to this main content
// area, there is also a single-row "action area", which is not
// scrolled and can contain a single actor. There are also convenience
// methods for creating a button box in the action area.
//
// If @params contains a 'body' parameter, that text will be displayed
// in the body area (as with addBody()). Alternatively, if it includes
// a 'bannerBody' parameter with the value %true, then @banner will
// also be used as the body of the notification when the banner is
// expanded. In this case, if @banner is too long to fit in the
// single-line mode, the notification will be made expandable
