added METADATA config item to enable/disable object metadata retrieval on proxy connect (defaults to True)
added @Pyro4.core.oneway decorator to mark a method as oneway, this will be retrieved in the metadata (so you don't have to set _pyroOneway manually anymore)
added _pyroMethods and _pyroAttrs, retrieved in the metadata (still unused at this time)
added info and get_metadata methods on the DaemonObject
requires serpent 1.6 because of set literal tweaks
