making master branch working again

[Kynneb]

• Fixed gui-packages, ilk packages and type_support packages
• Merge into master
• Test master
• Merge to stable branch
• Tag stable version

The broken packages were fixed and merged into master. I will test the master as-is once more and then tag as stable.

Test went through all good (installation need ~ 1h on my system).
