Problem with a language autonym (se)

OPEN This issue is open, waiting for action by Nemo_bis

The language name is not in CLDR, but in Names.php (added in unknown commit).

The Northers Sami Language is displayed as "Sámegiella" on Wikipedia. This is somewhat problematic, since "sámegiella" is a term for all Sami languages, and not specifically the Northern Sami language. The correct autonym would be "davvisámegiella", as it is also spelled like on the Northern Sami article about the language (Davvisámegiella)
