WebGUI bind IPv6

I just started to tinker around with vaping but I cannot seem to find relevant information about the IPv6 status of this project.

I would like to be able to bind the WebGUI onto an IPv6 address but the program crashes when I try to configure something like this:

    plugins:

      - name: http
        type: flask
        bind: [::]:7021
        debug: true
        static_url_path: /static
        server: self
        async: thread
        routes:
          /targets : graphsrv->targets
          /graph_data :
            methods:
              - POST
              - GET
            target: graphsrv->graph_data
          /graph : graphsrv->graph_view
          /overview_read_file : graphsrv->overview_read_file
          /: graphsrv->overview_view

Output:

The initial error is a yaml parse error because the value needs to be wrapped in quotes.

However once that is addressed, vodka still fails to parse it properly, ticket for the latter issue is created here: 20c/vodka#18

This fix seems to work. Thank you.
