Update 2012-10-19-integration.md

I saw it's better to have a internal page about convert then linking to external one... sorry for the small update. 
This is connected to the new convert page that was the bo.lt page before. Change request send couple of secs ago for that one.
Merge pull request #14 from dennisvdheijden/patch-3
