Florian Müllner 9c9da8a176 messageTray: Remove _lastNotificationRemoved()
No Source subclass used it to do anything special, and with sources
no longer having any UI representation on their own, doing anything
else isn't useful either, so just kill off that hook.

// @source: the notification's Source

//
// Creates a notification. In the banner mode, the notification
// 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.
//
// 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.
//
// By default, the icon shown is the same as the source's.
// However, if @params contains a 'gicon' parameter, the passed in gicon
// will be used.
//
// You can add a secondary icon to the banner with 'secondaryGIcon'. There
// is no fallback for this icon.
//
// If @params contains 'bannerMarkup', 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.
//
// If @params contains 'soundName' or 'soundFile', the corresponding
// event sound is played when the notification is shown (if the policy for
// @source allows playing sounds).
