Alexandre Bourget ec33732fbe Add multilingual support in Hugo
Implements:
* support to render:
  * content/post/whatever.en.md to /en/2015/12/22/whatever/index.html
  * content/post/whatever.fr.md to /fr/2015/12/22/whatever/index.html
* gets enabled when `Multilingual:` is specified in config.
* support having language switchers in templates, that know
  where the translated page is (with .Page.Translations)
  (when you're on /en/about/, you can have a "Francais" link pointing to
   /fr/a-propos/)
  * all translations are in the `.Page.Translations` map, including the current one.
* easily tweak themes to support Multilingual mode
* renders in a single swift, no need for two config files.

Adds a couple of variables useful for multilingual sites

Adds documentation (content/multilingual.md)

Added language prefixing for all URL generation/permalinking see in the
code base.

Implements i18n. Leverages the great github.com/nicksnyder/go-i18n lib.. thanks Nick.
* Adds "i18n" and "T" template functions..

Hugo provides the ability to both:
1. Order the way the keys for a taxonomy are displayed
2. Order the way taxonomyed content appears
## Ordering Taxonomies
Taxonomies can be ordered by either alphabetical key or by the number of content pieces assigned to that key.
### Order Alphabetically Example
<ul>
{{ $data := .Data }}
{{ range $key, $value := .Data.Taxonomy.Alphabetical }}
<li><a href="{{ .Site.LanguagePrefix }}/{{ $data.Plural }}/{{ $value.Name | urlize }}"> {{ $value.Name }} </a> {{ $value.Count }} </li>
{{ end }}
</ul>
### Order by Popularity Example
<ul>
{{ $data := .Data }}
{{ range $key, $value := .Data.Taxonomy.ByCount }}
<li><a href="{{ .Site.LanguagePrefix }}/{{ $data.Plural }}/{{ $value.Name | urlize }}"> {{ $value.Name }} </a> {{ $value.Count }} </li>
{{ end }}
</ul>
[See Also Taxonomy Lists]({{< relref "templates/list.md" >}})
## Ordering Content within Taxonomies
Hugo uses both **Date** and **Weight** to order content within taxonomies.
Each piece of content in Hugo can optionally be assigned a date.
It can also be assigned a weight for each taxonomy it is assigned to.
When iterating over content within taxonomies the default sort is first by weight then by date. This means that if the weights for two pieces of content are the same, than the more recent content will be displayed first. The default weight for any piece of content is 0.
### Assigning Weight
Content can be assigned weight for each taxonomy that it's assigned to.
```toml
+++
tags = [ "a", "b", "c" ]
tags_weight = 22
categories = ["d"]
title = "foo"
categories_weight = 44
+++
Front Matter with weighted tags and categories
```
The convention is `taxonomyname_weight`.
In the above example, this piece of content has a weight of 22 which applies to the sorting when rendering the pages assigned to the "a", "b" and "c" values of the 'tag' taxonomy.
It has also been assigned the weight of 44 when rendering the 'd' category.
With this the same piece of content can appear in different positions in different taxonomies.
Currently taxonomies only support the default ordering of content which is weight -> date.
