Title: Combine Previous Manifest with Current

- When `rev-manifest.json` is included in `gulp.src`, the old manifest
will be used to preserve data. This allows separate gulp tasks to
use the same manifest.
- Optionally supply a file name to `rev.manifest`. Defaults to
'rev-manifest.json'. Example: `rev.manifest({ name: 'manifest.json'
});
