For now Ville Pohjanheimo (yllapito at mozilla.fi) and I can update the AMO

AMO supports only one addon package so you would need one id for each 
language. Like the addon id is now "fi at dictionaries...".

As there's not much information how the signing works if you don't 
distribute the addon in AMO (unlisted addon) so it could be possible to 
have one id and just change the languages inside.

The other question is does user need to have multiple mozvoikko addons 
for different languages and how does that work out? Or does the user get 
just basic addon package from AMO and have the language/spelling 
dictionaries outside the addon?
