Fixes two problems:
 * Variants not being shown up, i.e. ca ca@valencia showing up both as "català"
 * pt showing up as "português do Brasil"

For the first one i've went the easy route of adding the languageCode if there's an @ in it
For pt i had to hardcode it since i found no other way to make Qt understand that for "pt" we mean portuguese from portugal
