Be compatible with HTTP/2

devd has the ability to serve content with TLS, it would be nice if HTTP/2 was enabled in that case to allow browsers to use it and benefit from it. This is useful for development environment to test how an app reacts to it.

Freakish timing! I was going to raise the same issue today - I've run into the dreaded HTTP/1.1 maximum of 6 open connections. HTTP/2 defaults to 100.
