[w3c/manifest] short_name to fall back to name & vice versa (#466)

I'm seeing developers with manifests where `name` and `short_name` are duplicates, which is ok, but shouldn't be required.

It'd be nice if the `name` and `short_name` members explicitly fell back to each other. This will hopefully avoid an implementation giving up on displaying a name because `short_name` was empty, yet `name` was already as short as it could be, eg "Facebook".
