Having the content page name in the log key for the distinct error logger isnt't very usable when you have an error in a commonly used partial.
Using the Page Kind reduces the amount of log entries. Here is an example from an error in the partial menu.html, used in all the page templates:
```

Built site for language nn:

Which is pretty good.
Before this commit, Hugo used `html/template` for all Go templates.
While this is a fine choice for HTML and maybe also RSS feeds, it is painful for plain text formats such as CSV, JSON etc.
This commit fixes that by using the `IsPlainText` attribute on the output format to decide what to use.
A couple of notes:
* The above requires a nonambiguous template name to type mapping. I.e. `/layouts/_default/list.json` will only work if there is only one JSON output format, `/layouts/_default/list.mytype.json` will always work.
* Ambiguous types will fall back to HTML.
* Partials inherits the text vs HTML identificator of the container template. This also means that plain text templates can only include plain text partials.
* Shortcode templates are, by definition, currently HTML templates only.
Fixes#3221
Using it for list pages doesn't work and has potential weird side-effects.
The user probably meant to range over .Site.ReqularPages, and that is now marked clearly in the log.
Will have to fix this in a better way later in relation to the non-renderable pages.
But this commit brings the Hugo Benchmark down to "only slightly slower" than master.
```
benchmark old ns/op new ns/op delta
BenchmarkHugo-4 10074504521 10071236251 -0.03%

benchmark old bytes new bytes delta

```
Which is something we can work with.
This is a pretty fundamental change in Hugo, but absolutely needed if we should have any hope of getting "multiple outputs" done.
This commit's goal is to say:
* Every file target path is created by `createTargetPath`, i.e. one function for all.
* That function takes every page and site parameter into account, to avoid fragile string parsing to uglify etc. later on.
* The path creation logic has full test coverage.
* All permalinks, paginator URLs etc. are then built on top of that same logic.

Changing it to PageOutput was a mistake. You may think that the increased parallelism should be a good thing.
But not so much with the increased lock contention and more complex concurrency model.
This commit fixes two different, but related issues:
1) Live-reload when a new shortcode was defined in the content file before the shortcode itself was created.
2) Live-reload when a newly defined shortcode changed its "inner content" status.
This commit also improves the shortcode related error messages to include the full path to the content file in question.
Fixes#3156
Lots of cleanups here:
- Refactor InterfaceToConfig and InterfaceToFrontMatter to use io.Writer.
- Simplify InterfaceToFrontMatter by wrapping InterfaceToConfig.
- Export FrontmatterType since we return it in DetectFrontMatter.
- Refactor removeTOMLIdentifier to avoid blindly replacing "+++".
- Update HandleJSONMetaData to return an empty map on nil input.
- Updates vendored goorgeous package and test for org-mode frontmatter.
- Add tests and godoc comments.
Coverage for parser package increased from 45.2% to 85.2%.
