Enable "strict" mode for NodeJS

Summary:
In particular, this changes the behavior of NodeJS in the following ways:

- Any attempt to get or modify the global object will result in an error.
- `null` values of `this` will no longer be evaluated to the global object and primitive values of this will not be converted to wrapper objects.
- Writing or deleting properties which have there writeable or configurable attributes set to false will now throw an error instead of failing silently.
- Adding a property to an object whose extensible attribute is false will also throw an error now.
- A functions arguments are not writeable so attempting to change them will now throw an error `arguments = [...]`.
- `with(){}` statements are gone.
- Use of `eval` is effectively banned.
- `eval` and `arguments` are not allowed as variable or function identifiers in any scope.
- The identifiers `implements`, `interface`, `let`, `package`, `private`, `protected`, `public`, `static` and `yield` are all now reserved for future use (roll on ES6).

Test Plan: Verified that Aphlict was still functional.
