Fixed bugs:

1) Send "remote side is typing" message only once. 
   This error caused at the client (applet) side, to always display the 
   "Remote party typing..." message even if there is no new message. 

2) Wrong behavior of connections list, pop-up.
   Clicking on the connection status list and opening the pop-up 
   always displayed also the open chat even if the client did not finished 
   to register. If the user has not yet registered (his name) the connect 
   is not possible.

3) Wrong behavior of application on remote disconnection.
   When a remote (client) has started to type a message and then terminated
   without sending the message. The support side got the termination message
   but also displayed to the supporter a warning that remote side still typing. 
   If the remote client has terminated this message has no meaning. 

4) Minimize and maximize now works properly.

5) Opening the extra options and choosing one of them now closes it automatically
   after the action has been performed.

Added/updated options:

1) Added client e-mail address inside the chat transcript.

2) Changed default sound on incoming message.
