Dan Winship 446910cb10 messageTray: move the summary notification out of MessageTray.actor 
With the old pre-boxpointer summary notifications, it sort of made
sense that the summary notification actor was a child of the message
tray. But there's no reason for that now, and in fact, it ends up
requiring special cases in some places since hovering over the summary
notification counts as hovering over the tray. So, fix this.

// will show an icon, @title (in bold) and @banner, all on a single
// line (with @banner ellipsized if necessary).
//
// The notification will be expandable if either it has additional
// elements that were added to it or if the @banner text did not
// fit fully in the banner mode. When the notification is expanded,
// the @banner text from the top line is always removed. The complete
// @banner text is added as the first element in the content section,
// unless 'customContent' parameter with the value 'true' is specified
// in @params.
//
// Additional notification content can be added with addActor() and
// addBody() methods. The notification content is put inside a
// scrollview, so if it gets too tall, the notification will scroll
// rather than continue 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. The action area can
// be set by calling setActionArea() method. There is also a
// convenience method addButton() for adding a button to the action
// area.
//
// @params can contain values for 'customContent', 'body', 'icon',
// 'titleMarkup', 'bannerMarkup', 'bodyMarkup', and 'clear'
// parameters.
//
// If @params contains a 'customContent' parameter with the value %true,
// then @banner will not be shown in the body of the notification when the
// notification is expanded and calls to update() will not clear the content
// unless 'clear' parameter with value %true is explicitly specified.
//
// If @params contains a 'body' parameter, then that text will be added to
// the content area (as with addBody()).
//
// By default, the icon shown is created by calling
// source.createNotificationIcon(). However, if @params contains an 'icon'
// parameter, the passed in icon will be used.
//
// If @params contains a 'titleMarkup', 'bannerMarkup', or
// 'bodyMarkup' parameter with the value %true, then the corresponding
// element is assumed to use pango markup. If the parameter is not
// present for an element, then anything that looks like markup in
// that element will appear literally in the output.
//
// If @params contains a 'clear' parameter with the value %true, then
// the content and the action area of the notification will be cleared.
// The content area is also always cleared if 'customContent' is false
// because it might contain the @banner that didn't fit in the banner mode.
