attempt to use a system.get and system.set module transformer

This is a VERY feeble attempt at what was described in https://github.com/google/traceur-compiler/issues/754#issuecomment-35076748

It's passing exactly zero tests.

But it might be able to work.

Basically the output is:

```javascript
  System.set('module-name', (function(__System, __Module) {
    var m = __System.get('dependency-normalized-name');
    return __Module({});
  }).call(this, System, Module));
```

There seems to be some issue with the way the bindings are working out. Any hints on what I might be doing wrong would be greatly appreciated.

Thanks for consideration as always.
