Frank Schmirler afe255aa0b Added server menu with list of clients. Connections can be terminated 
with the "red" key. The former main menu action of suspending live TV
moved to the "blue" key.

Squashed commit of the following:

commit 7175d7de91
Author: Frank Schmirler <vdr@schmirler.de>
Date:   Sun Nov 27 11:51:26 2011 +0100

commit 94aef85adc
Author: Frank Schmirler <vdr@schmirler.de>
Date:   Sun Nov 27 11:32:16 2011 +0100

    Moved "closing connection" log message to overload of cTBSocket::Close() in
    cServerConnection.

commit 9b91301d94
Author: Frank Schmirler <vdr@schmirler.de>
Date:   Fri Nov 25 00:24:37 2011 +0100

    Don't keep a pointer to the connection in components MulticastGroup
    structure as the connection may now be deleted from outside via menu.
