It now matches the [newer version of
typescript](https://www.typescriptlang.org/docs/handbook/namespaces-and-modules.html)
that suggest exporting
a namespace as an es6 module rather than declaring a module and exporting
that.
This also works better with browserify and looking up the type declaration
from the es6 import. So:
```
import * as tinymce from 'tinymce'
```
works and there is no need for importing it like:
```
import { tinymce } from 'tinymce'
```
