Breadcrumbs

Add breadcrumbs to your page.

• e.g. Home / Foo / Bar / Baz

This was based on:

• Breadcrumbs on jekyllcodex.org

I cleaned it up and added supported for relative URLs.

• _includes/breadcrumbs.html

    <div id="breadcrumbs">
      
  
        <a href="/code-cookbook/">Home</a>
  
          
            /
              
                  
                <a href="/code-cookbook/recipes/">Recipes</a>
              
          
            /
              
                  
                <a href="/code-cookbook/recipes/jekyll/">Jekyll</a>
              
          
            /
              
                  
                <a href="/code-cookbook/recipes/jekyll/snippets/">Snippets</a>
              
          
            /
              
                Breadcrumbs
              
          
  
    </div>
  

The code above always starts with Home. This may not make sense for pages like /about.html and /animals/index.html which are 1 level below / in terms of URL but they are not really below Home. So the top level could be Animals instead and Home can be reached through the navbar.
