Please see https://github.com/umdjs/umd/pull/63 and https://github.com/umdjs/umd/issues/35 for more information, but
this change prevents an HTML element with an id of `exports` from causing the UMD shim to incorrectly detect the environment as node.

As we require the template to be a `string` we now throw an error when given
any other data type. This should provide the developers with a meaningful
error rather than a cryptic TypeError from the murky depths of our source code.

Fixes #464

Fixes #445

Fixes #442

Made it eslint compatible.

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

+ minor fix for better error message when running specific render test

Fixes #415

- 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

Split the old Writer.renderTokens() into several small functions with a single responsible.

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.

Removed cache* functions altogether. mustache.parse is all that's
really needed.
