Holds app-specific data to be retrieved by the app on launch
As each app in the Apps Section screen is launched, the app's name is written to the /pps/system/navigator/appdata object. For example, if the user taps the Settings button as well as the BestParking button, the object will look like this:
@appdata [n]BestParking:: [n]Settings::
Each app can then read this object and retrieve any data published here.
