This information was previously scattered around in the forums and
mailing list. Add it to the official docs to make things easier for new
users.
Fixes#1167
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.
