ItemPath.fromUUIDString unnecessary as ItemPath(String) supports both

plain UUIDs and an /entity prefix. Tightened that up and removed the
fromUUIDString method for a simpler API. Also switched AgentPath(String)
to a path argument for consistency. New AgentPaths should be created
with AgentPath(new ItemPath(), String) instead.
