From 3842735e303f0bf6f46ed8cb659c92d8bb9bd137 Mon Sep 17 00:00:00 2001
From: Keith Packard <keithp@keithp.com>
Date: Wed, 3 Sep 2014 22:32:49 -0700
Subject: altosdroid: Use single object to pass data to UI

Instead of having separate messages for each piece of telemetry state,
package the whole mess up in one object and send it for any
change. This simplifies tracking within the UI by avoiding corner
cases during reconnect.

Signed-off-by: Keith Packard <keithp@keithp.com>
