Update homescreen event handlinghalibut_8.0.1halibut_8.0.0halibut/8.0.1halibut/8.0.08.0.18.0.0

Updated homescreen event handling logic to use the newer
Event_ShowWindow event instead of Event_TapShortcut, and match what
the other demo applications do. This fixes bringing the application
back to the foreground after switching away, which was not working.
As well, reindented main.cpp to improve readability.
