Title: Handle Query String and Fragments on Source URIs

This is especially important for the font hacks to make IE place nicely.

```sass
@font-face {
font-family: 'CustomSceneLight';
src: asset-url('scenepro-light-webfont.eot');
src: asset-url('scenepro-light-webfont.eot?#iefix') format('embedded-opentype'),
asset-url('scenepro-light-webfont.ttf') format('truetype'),
asset-url('scenepro-light-webfont.woff') format('woff'),
asset-url('scenepro-light-webfont.svg#CustomSceneLight') format('svg');
}
$custom-font-light: CustomSceneLight;
```

We need to change the path, add the digest, but preserve the ?#iefix tomfoolery.
