From 3f4d409f21bbb1f79f149a5ee66dcddaa505ddb1 Mon Sep 17 00:00:00 2001
From: Charles Kerr <charles.kerr@canonical.com>
Date: Sun, 9 Mar 2014 21:08:47 -0500
Subject: decouple the planner's states; need three separate sets: upcoming-now
 (for alarms in the current time), upcoming-calendar (to show events coming
 from the selected calendar date), and calendar-month (all the appointments in
 the month displayed in the menu).
