CLDR 24 changes lots of data formats

[cpence]

Version 24 of the CLDR is now out, and it's changed the way in which the plural rules and units elements (at least) are described. The release notes are here; I'd submit a pull request but I'm just not familiar enough with the file syntax to know what I'm doing.
