Title: Bug 802605 / Bug 802611 : app downloading icon in status bar

[Apps] Show app download icon in status bar if app(s) downloading
[Apps] Remove app downloading icon from status bar once download(s) complete

Also rewrote how callbacks for applications lifecycle management
are set and removed in the AppUpdatable object (part of the update
manager) so that it doesn't conflict with the install functionality.

Also added the final icon for the system download activity.
