Subject: Implement the FetchInventoryDescendents2 capability using the same
 code as WebFetchInventoryDescendents.

Enabling this by setting Cap_FetchInventoryDescendents2 = "localhost" in the [ClientStack.LindenCaps] section of OpenSim.ini downloads inventory via http rather than udp in later viewers.
