* Forcing the commit script to be run while on master branch
* Enforcing that when running the script no commits should have been previously staged (to avoid confusion over what gets added to the repo) Closes #41
* Adding extra check in the checklist for approvers to make sure that no `log.generate.short` has been left in the commit to be merged to master. If it's not the case it means that something went wrong in the pipeline and it should be checked.
* Adding colours in the commit script
