Mandoline: Implement basic "process per site" support
After fetching the resource, if it turns out it has a mime type that can
be handled by a known mojo app, then we grab the resources' URL, convert it
into a Site URL and use it as a qualifier to determine what process the mojo
app that will handle the resource should live in.
