Title: addSourceURLs

Hello TJ, little proposition for **addSourceURLs**
most of my packages use index.js as filename thus when i use addSourceURLs
and check the sources tab in chrome aIl I see is just see a bunch of index.js files
What do you think about adding this optional mapping function so I can use something like this to search file more easily
```js
builder.addSourceURLs(function(file) {
return file.split('/').join('-');
});
```
