just derped around for testing
Created this in order to implement chatrooms inside the server.
No real change, just what comes when coding everywhere, the standard
serialVersionUID was exchanged with a specific one, nothing else.
+ disconnect, I planed to use this, by server and client, but as my code
turned out only server uses it. This or the other way around StreamTools
has a new method now.
This was nearly changed everywhere.... it now has methods, to ask for
stuff on the server, and a read thread reciving everything that comes to
the RealClient.
I made all attributes private, and wrote getters, because it feels
better this way.
Has now all needed methods for basic funktionality, all stuff works,
only the sendExistingRooms() and whoisonline() feel like a mess, because
they throw wild exceptions without the Tread.sleep inside... it dosent
realy make the whole thing slower, but it feels bad... anyway the whole
thing is working, and in shape to get a GUI very soon.
