Add "redirects" configuration

[mbleigh]

We need to support redirection via the superstatic JSON config. Like so:

{
  "redirects": {
    "some/path/goes/here":"other/path/here",
    "some/wilcard/:segment/path":"other/wilcard/:segment/path",
  }
}

By default, redirects should use the 301 status. However, the user can specify a custom status like so:

{
  "redirects": {
    "some/path/here": [302, "other/path/here"]
  }
}

Note that this requires a new route parsing rule: colon-based segments. We can talk about this more, but basically need to be able to redirect segments dynamically and this is the best way I can think to do it. Open to comment.

What do you mean by "segments"?

[mbleigh]

URL segments. So :name matches an entire URL segment and can be used in the destination.

e.g. {"/some/:path/here":"/other/:path"} matches /some/thing/here and redirects to /other/thing

[scottcorgan]

That makes sense. I already have a module that will make those segments very easy.

Recommendations:

1. I recommend we use the "routes" object for redirects. It already handles redirects and it's one less config object in the json file.
2. I recommend we configure status codes like this:

{
  "routes": {
    "/some/path": {
      "status": "302",
      "path": "/some/other/path/redirectied"
    }
  }
}

This makes less confusion as to where the status and the path go in the array for the user.

We already handle redirects in the routing? I thought it was only rewrites. How do redirects currently work in routes?

[scottcorgan]

I lied. The only redirects that happen are for clean urls and directory indexes. We should add a redirects object.

[mbleigh]

Yeah, and you're right it should be plural since routes is plural.

[scottcorgan]

NOTE: providing a url redirects to that url. Providing a path, redirects only to that path

[mbleigh]

Let's do status, not statusCode. For one thing, we have generally used an underscore convention for Superstatic config, for another it's more succinct and I like it better.
