generate manifest.json with information of the static files

[tripodsan]

since the list of static files is know during deploy time, it can be included into the bundled distributor.

I'd suggest we remove the bundled distributor entirely, given that we have a good way of using GitHub as the distributor.

this is only a pre-step before we can merge the static-serving logic. As I mentioned somewhere else (can't remember where :-) Having the static delivery redirector (disty) bundled together with the html.js action saves us 1 action. so we still can have a disty per strain, but the config in the VLC is much easier, as we only need to handle 1 case.

Ok, let's just generate the manifest.json for now. I think it could serve as a good source of information for any static deployment mechanism. I will also include the content-hash of the files. eg:

{
  "styles.css": {
      "size": 1234,
      "hash": "..."
  },
  "favicon.ico": {
      "size": 1234,
      "hash": "..."
  }
}
