* Although my previous PR (#469) on this topic was merged, it caused
  [quite a discussion](https://github.com/janl/mustache.js/pull/469) about
  the clarity of the language I wrote.
* This commit seeks to clarify and improve the sentence under discussion.

As secure $ENVs are disabled for pull requests and those $ENVs are required for running browser tests on saucelabs.

+ updated readme with the fact that browser tests are only runned automatically when *merged into master*, not in the PR stage

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).

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

I've corrected the wrong variable name.

Fixes #346

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.
