port: add port globals

Browse source 
Expose all ports as globals, linking is then done by specifying
the global id of the ports.
Add method to destroy objects. not much security on this one but
yet but it should allow priviledged clients to kill connections
and other clients etc.
Make events on the global object. Implement the bind with the event,
handle destroy of the globals.
Add link properties
Use append to preserve the order.
