/*
replace all the internal links in an article to their chosen language interwiki, when such exists.
it uses 2 windows global variables, with defaults: 
translatelinks_target: chosen language code. defaults to 'en'. 
translatelinks_prompt: text for the menu item to activate the replacement
translatelinks_autoreplace: if set to true, no menu will be created, and the substitution will happen automatically when opening a new page

if you want to use it in any wiki project in any language, call it from [[meta:Special:MyPage/global.js]]
