Added missing package repo info

We are using Foundation in our project and noticed this warning. This is because the `package.json` file is missing the required `repository` information. This pull request adds it in.

```
npm WARN package.json angular-mm-foundation@0.2.0-SNAPSHOT No repository field.
```
