- Locale kit : made the language class live. It now uses ICU as a backend as expected

- Some changes in the locale roster to allow instanciating a language
- Locale preflet : use this new API instead of directly calling ICU
Side effect : all languages in Locale window are now displayed in the current locale. It makes more sense as otherwise the list would be unsortable. However it can get annoying if you mistakenly set a strange language as default.
