Nick Fitzgerald 161fce9d50 Expose objects and functions from the JavaScript global scope
These are bindings to JavaScript's standard, built-in objects and their methods
and properties.

This does *not* include any Web, Node, or any other JS environment APIs. Only
the things that are guaranteed to exist in the global scope by the ECMAScript
standard.
