How can I create a server-side auth token?

You can create server-side auth tokens as follows, using e.g. Ruby:

	@ziggeo = Ziggeo.new('APPLICATION_TOKEN', 'PRIVATE_KEY', 'ENCRYPTION_KEY')
	@grants = {
			create: {session_owned: true},
			read: {session_owned: true},
			update: {session_owned: true},
			destroy: {session_owned: true}
	}
	@auth_token = @ziggeo.authtokens.create(grants: @grants.to_json)
