Before Hugo this commit we set the pseudo page kind RSS on the page when output to RSS. This had some unintended side effects, esp. when the only output format for that page was RSS.
For the page kinds that can have multiple output formats, the Kind should be one of the standard home, page etc.
Fixes#5138
Before this commit you would typically use `.Scratch.Add` to manually create slices in a loop.
With variable overwrite in Go 1.11, we can do better. This commit adds the `append` template func.
A made-up example:
```bash
{{ $p1 := index .Site.RegularPages 0 }}{{ $p2 := index .Site.RegularPages 1 }}
{{ $pages := slice }}
{{ if true }}
{{ $pages = $pages | append $p2 $p1 }}
{{ end }}
```
Note that with 2 slices as arguments, the two examples below will give the same result:
```bash
{{ $s1 := slice "a" "b" | append (slice "c" "d") }}
{{ $s2 := slice "a" "b" | append "c" "d" }}
```
Both of the above will give `[]string{a, b, c, d}`.
This commit also improves the type handling in the `slice` template function. Now `slice "a" "b"` will give a `[]string` slice. The old behaviour was to return a `[]interface{}`.

Add a regex matcher for json types. Specifically support LD+JSON which
allows for google seo minification out of the box. Expanded JS/JSON
minification testing.
This extends the page grouping in Hugo with a template function that allows for ad-hoc grouping.
A made-up example:
```
{{ $cool := where .Site.RegularPages "Params.cool" true | group "cool" }}
{{ $blue := where .Site.RegularPages "Params.blue" true | group "blue" }}
{{ $paginator := .Paginate (slice $cool $blue) }}
```
Closes#4865
This also adjusts the pagination logic to allow for these new collections.
Note that we will follow up with a template function named `group` that will be the end user API. The `.Group` method on `Page` should be considered as internal.

Doing so was probably a mistake. This may be a breaking change for some people,
but it's easy to restore the previous behaviour in the layouts.
