sync Unstable and master branch
I added a branch, which i would like to use for frequent feature merges. Since the branch is likely to be more unstable i named it unstable.
If you agree i would change my workflow to merge all features into this unstable branch and then sync it regularly with the master branch, given it is in stable and good condition.
Changes for now to sync:
- improved stability regarding CI
- separated ci jobs into build testing and deploy (deploy stage is tested with this mr)
