Migrating code from 6.2 to 6.3

Qt Application Manager 6.3 cleaned up the APIs and manifest definitions concerning the Package, Application and Intent fields for icon, name and description. All three support the same API now, with the package's fields acting as a fallback for both the application and intent objects. Due to a clash between the property name and the function name in ApplicationObject, user code that called the Application.name(language) function before, now needs to replace this with Application.names[language].
