Changed debug logging

- stdout logs got rid of rustls messages and now are pretty styled
- logs are saved into the `debug.log` file in the launcher folder
  they're not filtered and contain all the messages
- toasts timeout fixed to 5 seconds
- added "save" button which will, well, not save logs
  but open `debug.log` file using `xdg-open`
