Clang: Move QLocalServer in ConnectionClient

Browse Source 
Before the QLocalServer was in the ConnectionServer so more than one
client could connect to the server. But we never used that possibility
which made the hand shaking much more difficult. It is now moved
in the client, so that there is always a QLocalServer.
