Changeset 217 for code/branches/network/src/network/ClientConnection.h

-implemented class ClientConnection:

• implements the network part of a client (analog to ConnectionManager for the server)
• again there is a receiver-Thread and a buffer
• (hopefully) clean disconnection and wait for connection

-extended dummyclient (dummyclient2.cc) to use new ClientConnection class
-make target client builds now dummyclient2
-adjusted the Makefile
