WoW v6.0.2 API updates + locales cleanup

Please double check line 722 change in `Carbonite/NxUI.lua` before merging - according to http://www.wowwiki.com/API_GameTooltip_AddLine there shouldn't be a 6th parameter in `GameTooltip:AddLine` but I'm not experienced enough to know for sure.

As can be seen from http://wowprogramming.com/utils/xmlbrowser/mindiff/AddOns/Blizzard_AchievementUI/Blizzard_AchievementUI.lua the function have only 5 parameters.
