Separator for interactive

[daKmoR]

As a user, I would like to see a clear separation between groups of menu points.

Describe the solution you'd like

      {
        type: 'interactive',
        query: 'What would you like to do today?',
        handle: 'action',
        symbol: '>',
        menu: [
           'outside walking', 'outside running',
           '---' // not selectable - special string or a special type like new Seprator();
           'inside cardgame', 'inside talking'
        ],
      },
