20cbc2c785 Add a BlackFriday option for rel="noreferrer" on external links 
Add a configuration option "noreferrerLinks". When set to "true" the "HTML_NOREFERRER_LINKS" flag is being passed to Blackfriday. Thereby all *absolute* links will get a "noreferrer" value for their "rel" attribute.

See #4722

✨ Implement Page bundling and image handling 
This commit is not the smallest in Hugo's history.

Some hightlights include:

* Page bundles (for complete articles, keeping images and content together etc.).
* Bundled images can be processed in as many versions/sizes as you need with the three methods `Resize`, `Fill` and `Fit`.
* Processed images are cached inside `resources/_gen/images` (default) in your project.
* Symbolic links (both files and dirs) are now allowed anywhere inside /content
* A new table based build summary
* The "Total in nn ms" now reports the total including the handling of the files inside /static. So if it now reports more than you're used to, it is just **more real** and probably faster than before (see below).

A site building  benchmark run compared to `v0.31.1` shows that this should be slightly faster and use less memory:

```bash

8717a60cc0 Change SummaryLength to be configurable (#3924) 
Move SummaryLength into the ContentSpec struct and refactor the
relevant summary functions to be methods of ContentSpec. The new
summaryLength struct member is configurable by the summaryLength config
value, and the default remains 70. Also updates hugolib/page to use the
refactored methods.

dd45e6d7e5 Lazy calculate WordCount, ReadingTime and FuzzyWordCount 
This avoids having to execute these expensive operations for sites not using these values.

This commit sums up a set of wordcounting and autosummary related performance improvements.

The effect of these kind of depends on what features your site use, but a benchmark from 4 Hugo sites in the wild shows promise:

```

BenchmarkHugo-4     21293005843     20032857342     -5.92%

bcd434794a Avoid splitting words for summary 
For people using autogenerated summaries, this is one of the hot spots in the memory department.

We don't need to split al the content into words to do proper summary truncation.

This is obviously more effective:

```
BenchmarkTestTruncateWordsToWholeSentence-4            300000          4720 ns/op           0 B/op           0 allocs/op

* RenderingContext's "mmark" has been changed to use MmarkRender
* Content_test.go added to cover content.go's functionality

67df33f500 Correct initialisms as suggested by golint 
First step to use initialisms that golint suggests,
for example:

    Line 116: func GetHtmlRenderer should be GetHTMLRenderer

as see on http://goreportcard.com/report/spf13/hugo

Thanks to @bep for the idea!

Note that command-line flags (cobra and pflag)
as well as struct fields like .BaseUrl and .Url
that are used in Go HTML templates need more work
to maintain backward-compatibility, and thus
are NOT yet dealt with in this commit.

First step in fixing #959.
