* 'master' of github.com:janl/mustache.js:
  allow using sections as context. Patch by dpree.

If a section key returns a function, it will be called
and passed both the unrendered block of text and a renderer
convenience function.

Given this JS:

  "name": "Tater",
  "bolder": function() {
    return function(text, render) {
      return "<b>" + render(text) + '</b>'
    }
  }

And this template:

  {{#bolder}}Hi {{name}}.{{/bolder}}

We'll get this output:

  <b>Hi Tater.</b>

As you can see, we're pre-processing the text in the block.
This can be used to implement caching, filters (like syntax
highlighting), etc.

You can use `this.name` to access the attribute `name` from
your view.

* defunkt/rake:
  Add descriptions to rake tasks (`rake -T` to see all)
  print => puts

lib/mustache.js is now always kept in sync with mustache.js
