Net changes

The client scanning part triggered a larger cleanup session than I initially imagined. The timing is probably not the best, but it will minimize the protocol part and make i quite stable. At the same time it will get easier to extend client/server functionallity because this will be implemented using RMI instead of protocol magic tags. This leaves only non-connection oriented packages to be specially handled. Currently this is the TICK packet ( from server to client) and the ACTION packet ( from client to server). When this is cleaned up I'll get into the new type of actors that provides WoW style collisions.
