Increases clarity on the different between `section` and `type`.
The current `section` information here is wrong (sections can *not* be specified in front matter). This caused quite the headache. This change fixes this and also adds `type`, since it *can* be specified in front matter.
As Hugo now supports more formats thanks to the new "external helpers"
feature recently introduced, and as requested by some people, I added
some lines in the doc:
* basically confirming it actually exists
* how to use it
* Add meta author, description and generator tags
* Add Hugo version beside the logo and in the footer
* Suggest the user to run `go get -u -v` to update dependencies
* Requires Go 1.3+ rather than Go 1.1+
* Improve rendering/formatting in some places
* Add trailing slash to URLs where appropriate
* GitHub redirects all http requests to https, update accordingly
General revisions to (hopefully) make the documentation
easier to understand and more comprehensive.
Revise "Strange EOF error" troubleshooting page to say that
a fix is in place for the upcoming Hugo v0.13.
Also add more external links, and cute icons from Font Awesome.
