Sync language-translation keys with dcrandroid

[macsleven]

No easy way to migrate translation from dcrandroid to dcrios and vise versa, currently creating translations on dcrios is a bit redundant. We use camel casing on dcrios as language keys and underscore pattern on android. The translation that already exists in the android translation file would have to be re-created for dcrios.

We can avoid this by refactoring the language-translation keys on dcrios. We can then create a script that generates a dcrios compatible language file from an existing dcrandroid language file
