Subject: * Drop cached inventory from the local region when a user crosses out
 into a remote region * May resolves inventory problems that occur when the
 user moves between two regions` * e.g. if the user moves to a second region,
 adds an inventory item, moves back to the original region then tries to
 manipulate that item * Not yet implemented for teleport
