Wrong filenames in src/package.json?

In the template for `src/package.json`, you have these lines:

```
"module": "<%= props.libraryName.kebabCase %>.js",
"jsnext:main": "<%= props.libraryName.kebabCase %>.js",
"typings": "<%= props.libraryName.kebabCase %>.d.ts",
```

but, in the output to `dist/`, these files are all named `index` rather than the library name. Or have I misunderstood something?

Compare the filename references in src/package.json with the files produced in dist/. Trace the generator output path and determine whether the package metadata should use the library name or index; done means the generated metadata consistently points to the actual output files.
