Taxonomy Term pages have variables in addition to those on "node"
pages. Documenting these variables with all the other node variables
makes them easier to find.
Fixes: #1155
Added clarification for RSS doc page.
* a little formatting to make key words jump out
* emphasize that you can create your own
* add how to link to the feed in <head>
* add what .RSSlink does
* added point that a link to an RSS feed should be of type application/rss+xml
Fleshed out aliases section, loading the "redirect" keyword so that it's easier to find. Specifically added a "how aliases work" section.
Added Discourse to comments section.
Fleshed out themes/customizing, because it seems to be the source of a lot of questions on the forum.
Added a bunch of clarifying narrative, looking at the discussion forum for what people are asking about, and what I myself was confused about.
* clearer separation of advantage of each style - server or client side - at the top
* inconsistent newlines (different column widths) so I just removed them from obvious paragraphs
* added that the highlight shortcode is not used for the client-side javascripts
* Hugo is taking crap for Pygments being slow, so tried to emphasize that's it's in Pygment's lap. I got your back, Hugo.
* On client-side added prism example
* More clarity on how the css and js needs to be added to your templates
* Explained how the client-side scripts work
Added bit about how the 404.html page has to be set to load automatically - auto on Github but needs config on other web servers.
Also tweaked the text a little to emphasize it's a node type, and explain a little more about where the 404 template should be saved.
Related to @bjornerik 's answer in this discussion: http://discuss.gohugo.io/t/inserting-data-from-data-file-into-content-file-newbie-question/1002/3 ... I figured I'd make myself useful and add the reference to the index function, on the go template primer page.
Also, I moved the reference links to the bottom.
A general comment: as good as these docs are, the primer at this point makes some assumptions about audience knowledge, so some might find it lacking. Once I understand better, I might make some more clarifying edits.
A couple of edits to clarify that the layout/partials folder can contain arbitrarily-named subfolders, since I found the examples using ``{{ partial "post/tag/list" . }}`` confusing. Some folders are named specifically to work a certain way with hugo, but although the examples use key functional section and taxonomy names like post and tag, it does not matter what they are called. Hopefully this will help other newbs.
