* Use an optimal release profile... load managers & hotkeys first, add a
splash, simplify app handler
* removed splashscreen, hopefully app boots fast enough anyhow
* No need to load transcription model on start now that its loaded on
demand & cleanup
* Make an unloaded model status
* tiny modification to unloading
* update comment
