Ehoogerbeets

Updated for iLib, and added many new rows for various i18n features. Other libraries slots need to be updated to put the check marks for all these new features.
Is indian grouping the second grouping separators? E.g., 1,00,000.00? If so, we could merge this into one single "grouping separator" and for libraries not supporting the indian group we use a different mark than :heavy_check_mark: alerting that. (This will also be apparent when we have test index in place)
