As a multi-lingual user I want to be able to change article languages quickly.
Languages overlay should show most common languages read by the user, and expand to show all languages available. This is done on desktop using compact language links. https://www.mediawiki.org/wiki/Universal_Language_Selector/Design/Interlanguage_links
**Acceptance criteria**
- Interlanguage links are only shortened when the list is longer than 6 items. If that happens, only 3 items are shown initially.
- The initial languages are decided based on the previous user selections (stored on a cookie), browser language info, and geo-ip information
- If there are more than 20 languages, organize the list by region
