no changes, just derped around
+serialVersionUID to help checking internal java stuff while
transferring Msg objects over network.

+Object object and its getter I hold this slot free for some stuff i may
need to transport over the stream ^^ "maybe I make object default and
cast the rest"
just derped around to test new stuff
This now gets its ip from main, what helps for testing, I through a
write method together to make different instances write different things
and now only use the Read Thread, because a Client is not supposed to
write stuff all the time :)
I call this ServerClient now, because its the place where I save stuff
about the client now, might be not a bright choise, but its easy to
maintain, in and out are in here now, and I even save the socket to
comunicate with the ReadClient here. StreamTools are used right from
here, so I could reduce stuff in the Server class.
I found out, that protokol only needs the thread running the
communication with the client and can now get all needed Stuff out of
there... maybe I make protokol an extra class.
