Add visual or audible alert support on connect/disconnect

Browse source 
The feature is detailed via the following option:

 --alert none|bell|blink

     Set alert action on connect/disconnect.

     It will sound the bell once or blink once on successful connect.
     Likewise it will sound the bell twice or blink twice on disconnect.

     Default value is "none" for no alert.
