Add new package sorting engine (disabled due to speed) that uses the native 3.0+ UILocalizedIndexedCollation to more closely mimic the official lists and provide localization for the table indexes. However, it UILocalizedIndexedCollation is unusably slow (about 7x slower than the previous implementation), so it is currently disabled (even if enabled, though, it is only used if UILocalizedIndexedCollation is available).
