Tapplet url from manifest

[karczuRF]

As it was proposed with RFC tapplet-registry.manifest.json structure stores data like this:

"source": {
          "location": {
            "npm": {
              "packageName": "@company-name/tapplet-another-name",
              "registry": "https://registry.npmjs.org/"
            }
          }
        }
      },
      "versions": {
        "1.2.2": {
          "checksum": "xyz"
        },
        "1.2.0": {
          "checksum": "xyz"
        }
      }

To download with http the npm package url is like this: https://registry.npmjs.org/tapplet-example/-/tapplet-example-0.0.2.tgz

Therefore package url should be created from registry/-/versions.tgz or "npm-full-http-url" field should be added to registry file.
