If you need to make sure only `hopscotch.js` and `hopscotch.min.js` are copied over into dist directory, it's cleaner to update copy:releaseWithBanner task, to pick up only nedded files

```
releaseWithBanner : {
        files: [
          {
            expand: true,
            cwd: '<%=paths.build%>/',
            src: ['js/hopstoch.js', 'js/hopstoch.min.js', 'css/*'],
            dest: '<%=paths.dist%>/'
          }
        ],
```
