This enables `AND` (`intersect`) and `OR` (`union`) filters when combined with `where`.
Example:
```go
{{ $pages := where .Site.RegularPages "Type" "not in" (slice "page" "about") }}
{{ $pages := $pages | union (where .Site.RegularPages "Params.pinned" true) }}
{{ $pages := $pages | intersect (where .Site.RegularPages "Params.images" "!=" nil) }}
```
The above fetches regular pages not of `page` or `about` type unless they are pinned. And finally, we exclude all pages with no `images` set in Page params.

* Improve the built-in Disqus template
Set `disqus_identifier`, `disqus_title`, and `disqus_url`
only if the user has explicitly provided them.
Do not load Disqus when the website is previewed locally,
otherwise it is very confusing.
* Use disqus_config instead of three global variables

reStructuredText doesn't have explicit section levels but sets them in
the order of appearance. Since level 1 is already set from the title in
the front matter it makes more sense to start with level 2 when
converting with rst2html.
This ensures the new "open 'current content page' in browser" works
on Windows, especially with Emacs and Vim.
Special thanks to @bep for coming up with the idea of the fix.

This commit adds a new `--navigateToChanged` and config setting with the same name, that, when running the Hugo server with live reload enabled, will navigate to the current content file's URL on save.
This is really useful for site-wide content changes (copyedits etc.).
Fixes#3643
This change is motivated by Netlify's `_redirects` files, which is currently not possible to generate with Hugo.
This commit adds a `Delimiter` field to media type, which defaults to ".", but can be blanked out.
Fixes#3614
Note that even with this setting enabled, the aliases themselves are preserved on the pages.
The big motivation for this change is to be able to use the alias definitions to generate `.htaccess` or Netlify's `_redirect` files with server-side redirects.
Fixes#3613
