Uc 85 - porting fbconnect.js to FacebookClient extension JS

This PR is an audit of the current usages of fbconnect.js, which will be removed from the code base once the switch to the facebook sdk v2.x is completed. 

It includes some code cleanup:
- CommentsLikes module had migrated to V2 but had never been cleaned up. Since it was calling some FB functions, I decided to clean up the code. Example usage: [Blog pages](http://lizlux.liz.wikia-dev.com/wiki/User_blog:Lizlux)
- CreateNewWiki was still referencing ComboAjaxLogin code, which has been deprecated. 
- Lot's of cleanup in CreateNewWiki.js

Although this is part of whitespace fix, shouldn't it be checked for type function?
