[xwiki-devs] [contrib] Move realtime-backend and realtime-wiki to xwiki-contrib

Hi, I'd like to shove these two projects over into xwiki-contrib github group. One is for the backend which supports realtime-wysiwyg and realtime-wiki and the other is the realtime-wiki (text editor). https://github.com/cjdelisle/xwiki-contrib-rtbackend https://github.com/cjdelisle/xwiki-contrib-rtwiki Thanks, Caleb
