Timothy Flynn b6093ae2e3 LibJS: Implement String.prototype.substr according to the spec ...

Fixes #6325

The JavaScript on the HTML Spec site that caused the crash is:
    window.location.hash.substr(1)

Of course, window.location.hash can be the empty string. The spec allows
for calling substr(1) on an empty string, but our partial implementation
wasn't handling it properly.
