[rules-users] Compatibility of Rule Flows from 4.0.7 to 5.0.0

[Mark Proctor]

You are a star, that saves us a lot of work :) I'm wondering if we can 
work this into the package reader and some how have it detect whether 
something is version 4 or 5 and convert first if it's 4, fancy having a 
look and seeing if that's possible?
