Allows standard module importing to work
Allows standard module importing to work

Sets main path in the package.json to use lib instead of scripts.

The following code:

```javascript
import { controls} from 'react-media-player';
```

Throws this error:
```shell
Module not found: Error: Cannot resolve module 'react-media-player' in
/Users/aaron/workspace/work/apps/disc/components/opinion/webpack/components
@ ./webpack/components/StimulusPlayer.js 13:24-53
```

I'm forced to use:

```javascript
import { controls } from 'react-media-player/lib/react-media-player.js';
```

It doesn't look like the project is has an `index.js` where you export
the objects you want. It looks like the `main` directive in the
`package.json` is wrong:

```json
"main": "scripts/react-media-player.js",
```

Changing the `package.json` to point to `lib/react-media-player.js`
fixes the issue.
