This fixes a small blooper introduced in a3f4339.
Error message thrown for invalid template type, should be equal on
the server and in the browser.

Clarifies and improves language in documentation

* 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.

Update UMD Shim to be resilient to HTMLElement global pollution

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.

Throw error when providing .render() with invalid template type

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

Added global Mustache definition

This reverts commit 2f51083565. Util is
not yet configurable, so issue links point to `mocha`.

`version` is currently a moot prop since git tags are used instead. More
info at https://github.com/bower/bower.json-spec/commit/a325da3.

Remove moot `version` property from bower.json
