In a list of languages to select autonyms must be unique so that
every user would know what to select.
* Batak Toba language in the Batak writing variant (bbc-batk) has
an autonum in the right script now. This is taken from the Indonesian
Wikipedia article "Surat Batak".
* Similarly to the practice with pa -> pa-guru:
* iu for Inuktitut in the Canadian script redirects to ike-cans.
* ks for Kashmiri in the Arabic writing redirects to ks-arab.
* tg for Tajik in the Cyrillic script redirects to tg-cyrl.
* zgh has an updated autonym, taken from Ethologue.
* zh-classical redirects to lzh, similarly to zh-yue -> yue.
Addressing issue #207
Such language codes were not listed in ULS language list.
Root cause was $.uls.data.getLanguagesByScriptGroup was returning
a map of script groups, which contained only resolved language codes.
And later in append method of jquery.uls.lcd.js, there is a check if
that language code is part of languages list passed as option to uls()
call. This test fails and the language code does not get added to display.

utils.getLanguagesByScriptGroup() runs on the object's languages
property and not on all the langdb languages. This caused
the redirects to be counted as languages. I fixed this,
and added a test to prevent it.
Also update JS langdb, because it went out of sync in of
the previous commits.
This is supposed to allow adding special languages.
This region's section is hidden by default and can be enabled by
passing different options to the lcd object.
