Title: Force no-caching on st, no need for send

Setting the caching options on st and patching its own `streamFile()` function onto its `cachedFile()` function mean that nothing gets cached. This means we can use the same module for static assets in all envs.

Also, as a bonus, this patches the `error()` function too, so we get pretty error pages for 404s.
