  1. Use custom classifications (tags, categories, ...) 

    We used to classify posts with tags & categories.

This patch adds a generic way to define & use your own classifications through `site.config[:classifications]` by adding `tags` like behavior to site & posts for added classifications.

Let's say you want classify Post by referring to Project(s), Customer(s) and Layout(s) you can now simply add the following to `_config.yml` :

```
classifications:
  - projects
  - customers
  - layouts
```

And start using those classifications like you would with `categories` or `tags` :

Add the following to a Post:

```
projects:
  - project1
  - project2
layout:
  - grid
  - responsive
```

And then use the following in any template :

```
<h2>Projects</h2>
<ul>
{% for project in site.projects %}
  <li>{{ project | first }}</li>
{% endfor %}
</ul>
```

You can also access classifications through `classifications` methods of `Site` and `Post` if you're not in a Liquid template context (ie. when writting a Jekyll plugin) :

```
module Jekyll
  class CustomGenerator
    def generate(site)
      related_layouts = {}
      site.classifications['projects'].each do |project, posts|
        related_layouts[project] = posts.map{ |post| post.classifications['layouts'] }.flatten
      end
      # ...
    end
  end
end
```
