git kill branchname

@charlierudolph Aaaaahhhh, for some reason some commits meant for this PR ended up in an already merged PR. I was messing around with `git extract` while being distracted on the resource planning call, so that's my (super lame) excuse... Anyways, please take a look at https://github.com/Originate/git-town/commit/738e3e76158a4803c5695abf71349b21d02033f5, and comment there. I will implement the corresponding fixes in this pull request, and once this gets merged its all going to be kind of okay again...  :smile: 
The reason why I do this now is that it is a royal PITA to compile these release notes retroactively. I want to get as much as possible into them as part of feature branches. I'm fine with adding the commit SHA later, but the feature name and the issue should be added as part of features. This also seems more consistent.
