Acquire Item - Item to acquire
When an item is instantiated it will add it self to the local list in
the Owner Acquire class. Derived classes will then call QueueURI to
register all the URI's they wish to fetch for at the initial moment.
Two item classes are provided to provide functionality for downloading
of Index files and downloading of Packages.
