Switched steamworks.GetList to ISteamUGC
Added 3 new types for steamworks, GetList() - "followed", "friend_favs", "favorite"
Added "Followed" and "Favorite" sections to Addons menu
Subscribing to addons with "child" required addons from in-game now displays a nice message telling you which addons you should also install with quick and easy buttons to do so
Translations for the new addons menu stuff
