- Bring back the shutdown splash, with the tweak that is blanks out after 700ms
- Restore the non-Latin transliteration originally from https://github.com/akuker/RASCSI/pull/449 which was lost when the `common` package was introduced
- Bump to the latest libraries, while removing implicit dependencies from requirements.txt
- Shorter duration of the startup splash
- Reintroduce shell shutdown/reboot methods for use with the Web UI. This addresses https://github.com/akuker/RASCSI/issues/538 (the ctrlboard client will continue to use the built-in rascsi system calls which are slightly faster)
- Remove overt references to RPi. This addresses https://github.com/akuker/RASCSI/issues/990
- Other refactorings
