Fix bower package

Bower package reference to `main` needs to be a directory path (like package.json). It should also be the un-minified version by default.

For example running `bower info Colors.js` reveals no `main`, and through the programmatic API:

```js
bower.commands.list().on('end', function(packages) {
  for (var packageName in packages) {
    console.log(packages[packageName].pkgMeta.main);
    // Others yield './somefiles.js' but this one is `undefined`
  }
});
```
