+Subject: [PATCH] Applet: run full Applet::save when a config value changes
+
+Plasma had two timers for configuration saving:
+ - One applet specific, which eventually calls Applet::save
+ - One at a corona level, which eventually calls KConfig::save
+
+The former was incorrectly removed because it wasn't hooked up to
+anything useful, but the real bug is that it should have been.
+
+When a value changes in the KConfigPropertyMap we need to run through
+Applet::save to sync that config loader with our main config. This
+implicitly emits the configNeedsSaving which will trigger corona to sync
+to disk.
