This commit contains a restructuring and partial rewrite of the shortcode handling.
Prior to this commit rendering of the page content was mingled with handling of the shortcodes. This led to several oddities.
The new flow is:
1. Shortcodes are extracted from page and replaced with placeholders.
2. Shortcodes are processed and rendered
3. Page is processed
4. The placeholders are replaced with the rendered shortcodes
The handling of summaries is also made simpler by this.
This commit also introduces some other chenges:
1. distinction between shortcodes that need further processing and those who do not:
* `{{< >}}`: Typically raw HTML. Will not be processed.
* `{{% %}}`: Will be processed by the page's markup engine (Markdown or (infuture) Asciidoctor)
The above also involves a new shortcode-parser, with lexical scanning inspired by Rob Pike's talk called "Lexical Scanning in Go",
which should be easier to understand, give better error messages and perform better.
2. If you want to exclude a shortcode from being processed (for documentation etc.), the inner part of the shorcode must be commented out, i.e. `{{%/* movie 47238zzb */%}}`. See the updated shortcode section in the documentation for further examples.
The new parser supports nested shortcodes. This isn't new, but has two related design choices worth mentioning:
* The shortcodes will be rendered individually, so If both `{{< >}}` and `{{% %}}` are used in the nested hierarchy, one will be passed through the page's markdown processor, the other not.
* To avoid potential costly overhead of always looking far ahead for a possible closing tag, this implementation looks at the template itself, and is branded as a container with inner content if it contains a reference to `.Inner`
Fixes#565Fixes#480Fixes#461
And probably some others.
If content pages are fully rendered in a list page, footnotes that use
the same reference (`[^fn]`) will have duplicated anchors. This change
builds on #526 to put the page filename (`Page.File.Name`) as part of
the anchor for a footnote.
This would fix discussion [116](http://discuss.gohugo.io/t/footnote-references-are-duplicated-on-list-pages/116).
- The config file can provide FootnoteAnchorPrefix, which will be used
by blackfriday when rendering to HTML. A value of `q:` has the effect
of making the anchor for a footnote `[^footie]` be `fn:q:footie`. The
default is `""`.
- The config file can provide FootnoteReturnLinkContents, which will be
used by blackfriday when rendering to HTML. A value of `^` has the
effect of making the return link be `^` instead of `[return]`.
Modified markdownRender and markdownRenderWithTOC in hugolib/page.go to
use the same flags and extensions as were previously used when we simply
called blackfriday.MarkdownCommon to convert Markdown to HTML. These
flags/extensions were dropped during the refactor that added the
`.TableOfContents` page variable, and caused features like Markdown
tables to no longer work.
Modified the expected output for TestTableOfContents in page_test.go,
apparently changing the flags/extensions caused an `—` to become
`–`.
Added TableOfContents field to hugolib.Page struct. New function
getTableOfContents is used in convertMarkdown to set the TableOfContents
field.
Added new test file hugolib/page_toc_test.go with a simple test of the
new functionality.

A sample config.yaml for a site might contain:
```yaml
permalinks:
post: /:year/:month/:title/
```
Then, any article in the `post` section, will have the canonical URL
formed via the permalink specification given.

* Add `.Truncated` bool to each page; will be set true if the
`.Summary` is truncated and it's worth showing a "more" link of some
kind.
* Add `Params` to the site config, defining `.Site.Params` accessible
to each page; this lets the site maintainer associate arbitrary data
with names, on a site-wide basis.
* Provide a `First` function to templates:
* Use-case: `{{range First 5 .Site.Recent}}` or anything else which
is a simple iterable provided by hugolib
* Tests by me for `.Truncated` and `First`
Also @noahcampbell contributed towards this:
* Add UnitTest for `.Site.Params`:
> Digging into this test case a bit more, I'm realizing that we need

> future.
Sample config.yaml:
```yaml
title: "Test site"
params:
Subtitle: "More tests always good"
AuthorName: "John Doe"
SidebarRecentLimit: 5

The render code path would use a fallback if there was an exception.
This change instead relies on explicit declaration of the layout to use
and includes a check to see if the layout indeed exists before
attempting to render it.
If a file named index.html exists in a directory, or root, it will be
rendered as if ugly urls are turned on. This allows for top level
content to not need a supporting layout file and content in content.
This change should not affect anyone who is using the perscribed way.
I also cleaned up a bunch of one off functions in site.go.
Allow content that is not markdown and does not need to be rendered to
exists in the content directory. Currently any valid html or xml
document can exist. Templates are applied to these documents as well.
If you need to have content that doesn't have templates or AbsUrlify
like operations, then continue to put this content in static and it will
be copied over.
As pages are read from the target, they will be assessed if they should
be rendered or not. The logic for IsRenderable is in the parser/page.go
and looks for anything exception '<'.
filepath was used inconsistently throughout the hugolib. With the
introduction of source and target modules, all path are normalized to
"/". This simplifies the processing of paths. It does mean that
contributors need to be aware of using path/filepath in any module other
than source or target is not recommended. The current exception is
hugolib/config.go
It started with wanting to move templates in template bundles and the
rest followed. I did my best to start grouping related functions
together, but there are some that I missed. There is also the method
Urlize that seems to be a special function used in both worlds. I'll
need to revisit this method.
Allow full control of summaries which can be rendered as html rather
than text. Using a `<!--more-->` html comment in your markdown / rst
you can indiciate where the summary should end and have the summary
converted to html.

because the url lacks a trailing /, many webservers will issue a
redirect to the canonical url with trailing slash for directory index
w/index.htm(l).
Append a slash to avoid this.
The filename path was being split using a unix specific path seperator. This fix uses the os.PathSeperator to ensure proper evaluation regardless of platform.
