This commit also pulls down the log level for a set of WARN statements to INFO. There should be no ERRORs or WARNINGs in a regular Hugo build. That is the story about the Boy Who Cried Wolf.
Since the WARN log is now more visible, this commit also improves on some of them, most notable the "layout not found", which now would look something like this:
```bash
WARN 2018/11/02 09:02:18 Found no layout for "home", language "en", output format "CSS": create a template below /layouts with one of these filenames: index.en.css.css, home.en.css.css, list.en.css.css, index.css.css, home.css.css, list.css.css, index.en.css, home.en.css, list.en.css, index.css, home.css, list.css, _default/index.en.css.css, _default/home.en.css.css, _default/list.en.css.css, _default/index.css.css, _default/home.css.css, _default/list.css.css, _default/index.en.css, _default/home.en.css, _default/list.en.css, _default/index.css, _default/home.css, _default/list.css
```

Long identifiers will give errors on the format:
```bash
_default/single.html:5:14: executing "main" at <.ThisIsAVeryLongTitl...>: can't evaluate field ThisIsAVeryLongTitle
```
Hugo use this value to match the "base template or not", so we need to strip the "...".
Fixes#5346
`*json.UnmarshalTypeError` and `*json.SyntaxError` has a byte `Offset`, so use that.
This commit also reworks/simplifies the errror line matching logic. This also makes the file reading unbuffered, but that should be fine in this error case.
See #5324
We do that by re-render visited pages that is not already in the stack. This may potentially do some double work, but that small penalty should be well worth it.
Fixes#5281
The main item in this commit is showing of errors with a file context when running `hugo server`.
This can be turned off: `hugo server --disableBrowserError` (can also be set in `config.toml`).
But to get there, the error handling in Hugo needed a revision. There are some items left TODO for commits soon to follow, most notable errors in content and config files.

In short:
* Avoid double tolower in MakeSegment
* Use MakePathSanitized for taxonomies in pageToPermalinkTitle; this matches what MakeSegment does.
* Move the "double hyphen and space" logic into UnicodeSanitize
The last bullet may be slightly breaking for some that now does not get the "--" in some URLs, but we need to reduce the amount of URL logic.
See #4926
When constructing permalinks, ensure that most inputs used as path
segments are normalized with PathSpec.MakeSegment instead of
PathSpec.URLize.
The primary exception to that rule is with taxonomy titles in
pageToPermalinkTitle(). The approach taken here is to use URLize for
taxonomy pages. Everything else will use MakeSegment. The reason for
this exception is that people use taxonomies such as "s1/p1" to generate
URLs precisely they way they wish (see #5223). Tests have been added to
check for this case.
Fixes#4926
Previously, calls to *Page.Eq(nil) would always return false because the
unwrapPage func didn't support the nil case. Add support for unwrapping
nil to a *Page.
Fixes#5043
In Hugo `0.49` we improved type support in `slice`. This has an unfortunate side effect in that `resources.Concat` now expects something that can resolve to `resource.Resources`.
This worked for most situations, but when you try to `slice` different `Resource` objects, you would be getting `[]interface {}` and not `resource.Resources`. And `concat` would fail:
```bash
error calling Concat: slice []interface {} not supported in concat.
```
This commit fixes that by simplifying the type checking logic in `Slice`:
* If the first item implements the `Slicer` interface, we try that
* If the above fails or the first item does not implement `Slicer`, we just return the `[]interface {}`
Fixes#5269
Introduce new page position variables in order to fix the ordering issue
of `.Next` and `.Prev` while also allowing an upgrade path via
deprecation.
`.NextInSection` becomes `.NextPageInSection`.
`.PrevInSection` becomes `.PrevPageInSection`.
`.Next` becomes a function returning `.PrevPage`.
`.Prev` becomes a function returning `.NextPage`.
Fixes#1061
Given this content:
```bash
archetypes
├── default.md
└── post-bundle
├── bio.md
├── images
│ └── featured.jpg
└── index.md
```
```bash
hugo new --kind post-bundle post/my-post
```
Will create a new folder in `/content/post/my-post` with the same set of files as in the `post-bundle` archetypes folder.
This commit also improves the archetype language detection, so, if you use template code in your content files, the `.Site` you get is for the correct language. This also means that it is now possible to translate strings defined in the `i18n` bundles, e.g. `{{ i18n "hello" }}`.
Fixes#4535
