- Refactor the way apps work: Instead of a C interface, they are now C++ classes. The main reasoning is that attaching data to an app was cumbersome. Having different implementations for different kinds of apps was cumbersome too. (3 or 4 layers of manifest nesting for the TactilityC project) - External apps are still written in C, but they get a createData/destroyData in their manifest, so: - External apps now have their own manifest. - All functions in the original AppManifest are removed and replaced by a single `createApp` function - External apps now automatically register (each app individually!) when they run the first time. As a side-effect they become visible in the `AppList` app! - Adapted all apps for the new interface. - Adapted all internal logic for these changes (Gui, ViewPort, Loader, AppContext, AppInstance, etc.) - Rewrote parts of Loader to use std::shared_ptr to make the code much safer. - Added a refcount check for the `AppInstance` and `App` at the end of their lifecycle. Show warning if refcount is too high.
