This is still a first draft - the message types will surely change. -corrected ids and added service classes. -Added disc/msg/chat/cache/file messages -Extended serialiser to handle service extensions. -corrected IpAddrPort code. -More debugging code. -Added some tests. git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@270 b45a01b8-16f6-495d-af2f-9b41ad6348cc
