Covers the project with browser tests, not only V8 via node/iojs. Tests are runned with [zuul](https://github.com/defunctzombie/zuul) which
provides simple local browser testing, aswell as cloud testing on multiple browsers with [saucelabs](http://saucelabs.com).

Added `-v` option to CLI, bugfix for rendering `Number` when it was the
context, and specified files in package.json for cleaner `npm install`.

Good npm citizens should specify which files a npm module consists of
so module users dont have to download all the unnecessary things.

CLI used to render a mustache template with a data view, writes the template into stdout when successfull. Otherwise meaningfull errors into stderr.

Fixes #424

- Documented required version of npm while developing
- Use the latest npm client for node >= v0.8 on travis

Special quirks to get node v0.6 supported:
	- npm client v1.3.26 on travis
	- jshint 2.4.4 as >= 2.5.x breaks

This change allows the AMD define signature to match what common AMD optimizers use to find define calls that need naming.
Also updates the volo package.json entry so that the correct version of mustache can be fetched properly.

The goal is to reduce the number of files downloaded by ignoring the test directory

Fixes #249

This commit is a complete rewrite of the core mustache.js file with two
main goals: 1) a major performance boost and 2) better compliance with
the mustache spec.

In order to improve performance templates are pre-compiled to JavaScript
functions. These compiled functions take a view, a partials object, and
an optional callback as arguments. They are cached to prevent
unnecessary re-compilation of an already compiled template. Both of
these enhancements facilitate a generous boost in performance.

A few other notes:

- The mustache.js file is now both browser and CommonJS ready without
  any modification.
- The API exposes two main methods: Mustache.compile and
  Mustache.render. The former is used to generate a function for a given
  template, while the latter is a higher-level function that is used to
  compile and render a template in one shot. Mustache.to_html is still
  available for backwards compatibility.
- The concept of pragmas is removed to conform more closely to the
  original mustache spec. The dot symbol still works to reference the
  current item in an array.
- The parser is much more strict about whitespace than it was before. The
  rule is simple: if a line contains only a non-variable tag (i.e. not
  {{tag}} or {{{tag}}}) and whitespace, that line is ignored in the
  output. Users may use the "space" option when compiling templates to
  preserve every whitespace character in the original template.
- The parser is able to provide detailed information about where errors
  occur when parsing and rendering templates, including the line number
  and surrounding code context.

Use fancy regex to auto-fill the version number.
Closes #37.
