The missing language names

[Mooncat]

Could someone please add the missing language names for the locale drop-down in "Other settings"?
They have bugged me for awhile.

According to https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes
Their names should be Slovenčina (sk), Slovenščina (sl) and Shqip (sq).

Also, I see that some names are native but some are not, should we make them the same?
Though some tricky characters are still not supported by the default font, like ไทย (Thai).
