add ability to proxy requests

Add to gmid the ability to forwad a request to another gemini server and
thus acting like a reverse proxy.  The current syntax for the config
file is

	server "example.com" {
		...
		proxy relay-to host:port
	}

Further options (like the use of custom certificates) are planned.

cf. github issue #7
