TypeError: goog.isString is not a function

I ran into an issue where when I use Closure Templates standalone I get the following error: `test.js:20 Uncaught TypeError: goog.isString is not a function`

test.html

```

The Hello World of Closure Templates

document.write(examples.list());

```

test.soy

```
{namespace examples}

/**
* List
*/
{template .list private="true"}

{call .item}
{param title}
{msg desc=""}Hello World{/msg}
{/param}
{param description}
{msg desc=""}Lorem ipsum dolor sit amet{/msg}
{/param}
{param value: 1 /}
{/call}

{/template}

/**
* List item
*/
{template .item private="true"}
{@param title: string}
{@param description: string}
{@param value: int}

{$title}

{$description}

{/template}
```

The idea here was that I wanted to make a template out of the list item structure. But I also need to localize some of the text.

It wasn't clear to me how I could pass strings from `{msg}` as params - so I tried this which compiled, but fails in the browser because of missing `goog.isString`.

Reproduce the browser failure using test.html, test.soy, the generated test.js, and soyutils.js, then inspect how the standalone runtime handles the compiled template and localized message parameters. Done means the example renders the list item in the browser without the goog.isString error and supports the intended localized text.
