onClose and onError events

SSH connection could be interrupted in a middle.
To handle this situation added event:

  onClose: function( has_error, command ) {
    //has_error is true if session has bin interrupted.
    //command is latest command that was processing and did not finish.
    console.log(command);
  },

onError: function ( err, type, close) {
        console.log( "onError" );
        console.log(err);
        console.log(type);
        console.log(close);
      },

Initial release

• time for each command
• status for each command
