- Implemented `LaunchId` to keep track of the apps that are started - Implemented `FileSelection` app to select existing and/or new files. - Moved some re-usable file functionality to `tt::file::` - Renamed `Files` app to `FileBrowser` - Updated `Notes` app to use new `FileSelection` functionality, and cleaned it up a bit. - General code cleanliness improvements
