Created fooCodes interfaces to go along with invocation service

packages. These contain all the message codes as well as error response
codes that are used by a particular invocation service.

Also changed client.LocationManager to client.LocationDirector and
chat.ChatManager to chat.ChatDirector to go along with the new philosophy
of naming the client-side managing entity for an invocation service a
director.

Also elimitated cocktail.util.Codes since it's no longer used as a central
repository for codes (instead they are in InvocationCodes and its
derivatives).
