Resolves #73
I took a slightly different approach to the problem than originally spec'd in the issue. Rather than bundle all translations with the firmware, which would bloat the firmware binary and potentially limit the number of locales we could support in the future, I opted to store all translations on the microSD card and, if not present, fall back to English as the default baked-in language.
Just as a note for future reference, the function that loads translations from SD (
translations
) could trivially be updated to search in multiple locations if someone in the future did want to explore bundling compressed translations in the firmware.As part of this work, I also added back the ability for settings to persist (also via microSD) so users don't have to constantly be going into the settings menu just to change their default language.
