Title: Add underscore and camelize to String.prototype.

I thought that these methods mix automatically to String.prototype because tests passes with this:
```
if (Ember.EXTEND_PROTOTYPES) {
same('innerHTML'.underscore(), 'inner_html');
}
```
But that code is never called.
Q: How to run tests with extended prototypes?

Thanks.
