+/**
+ * Application scanner.
+ * Using AppArc application information, keeps menu application
+ * items up-to-date.
+ *
+ * Operation is asynchronous (because AppArc startup is asynchronous):
+ * 1. ConstructL(): invokes iApaLsSession to build app list (async).
+ * 2. RunL(): App list is complete - appscanner update entries with application.
+ * 4. HandleAppListEvent(): change in app list, go back to step 2.
+ *
+ * App scanning does the following:
+ * - Applications present in the system but not appearing in the menu are added
+ *   to the appropriate folder.
+ * - Hide hidden applications, show non-hidden applications (flag "hidden").
+ * - Hide / show MMC-related items, according to whether MMC is present or not
+ *   (flag "missing"). Keep an MMC history, purge old MMC-based menu items
+ *   (== missing menu items whose MMC card has not been seen for long).
+ * - Observing AppArc (and MMC, etc etc) to keep the menu data up
+ *   to date continuously.
