Allow to transform anon defines to named. - WIP

This is a first go at deanonimizing amd modules so they just work.

We could do that, but there are cases where the dir is something like `libraryjs/dist/library.min.js` in that case we are interested in getting 'define('library')` 

I'd use the file name without dots and  kebab case see https://github.com/abuiles/broccoli-amd-transforms/commit/69f6d6ec0d0caa07bc2aa361e7c05f1fcaa84325
