Aaron Lindsay 147a00e429 Only serve over HTTPS, optionally auto-generating certificates
Because MoneyGo requires sending passwords and session cookies, we
should never serve over HTTP. While we're at it, make it more convenient
for folks to test this out by adding a config option to auto-generate
self-signed certificates.
