Normalizing CHANGES.txt (#313)

* This normalization basically adds the [Unit_Name] in front of the issue when it is obvious and when it is missing
Added the [Domains] unit name (as in the java package name)
Didn't touch the issues changelog prior to v0.7

This resolves #270

* Updated according to Sebastian's code review
