diff 8.x-1.0-rc1

Diff is pretty much stable and we feel it's time for a release!

Since Beta 2, only minimum amount of breaking changes have been done. Most importantly, the configuration / diff builder settings handling wasn't clean and was overhauled.

Experimental support to display images in diffs is added. We don't know yet how to make this more pluggable, thus it's a hardcoded special case. #2840566: Make rich diff pluggable

Remaining major wish-issues have been promoted for visibility, however they are not release relevant.
We'll provide an overview about limitations of the current situation with the release and create another roadmap for future focus topics.
