Dan Stillman c2b77890c3 Fx60 compatibility: Fix issues with JS code modules
- The Mozilla CommonJS loader is no longer available, so bundle the
  Fx52 version of it
- Strict mode is enforced
- `this` is only defined as a global object in .jsm files, not .js files
- `this` can't be converted to a string for BackstagePass test, so check
  for presence of Components.utils.import instead
- The return value from import() is no longer available
