Return 404 when file not found

[yoshuawuyts]

When a file is not found status is set to 500 and not 404. A workaround is easy, but it'd be more elegant if it was supported out of the box.

Not sure if this needs adjusting in send/index.js:79 or if it should be overwritten here.

what's the err.code you're getting? it should just return and fallback to the default koa 404

Requests to files that exist get handled without a problem though.

well there's an error right there :p that's what it's a 500

if you can repro with a little stand-alone script with just koa-static I can check it out

Turns out I was yielding the whole module. Woops :p
