From 655218b7df40b3e159119933a4fa18efca2ff940 Mon Sep 17 00:00:00 2001
From: Lukas Fleischer <calcurse@cryptocrack.de>
Date: Thu, 15 May 2014 14:37:49 +0200
Subject: ui-todo: Large-scale refactoring

This is a complete overhaul of the TODO list user interface. The new
implementation uses the generic list box panel.
