Update some urls

[mwu2018]

1. Use https instead of http in url:

             {
             "type": "wms",
             "name": "Radio Licenses - ACMA",
             "id": "54a553a0",
             "url": "http://gis.aremi.data61.io/acma/wms",
              ...
             "legends": [
               {
                 "url": "http://geo-prototype1.aremi.d61.io/acma/wms?service=WMS&request=GetLegendGraphic&width=20&height=20&layer=acma_sites&format=image%2Fpng&.png"
               }
             ],
            ...
           },

   Note that geo-prototype1.aremi.d61.io does not exist.

2. Change "Australia Post Locations" url to https://tiles.terria.io/static/auspost-locations.csv

           {
             "type": "csv",
             "name": "Australia Post Locations",
             "url": "data/auspost-locations.csv",
             "activeStyle": "State",
             "id": "YUeesYKH",
             "shareKeys": [
               "Root Group/National Datasets/Habitation/Australia Post Locations"
             ]
           }
