Credits

While I went and figured out how to do all of this, this integration is based on the one I found for Beyond Compare's beta integration: https://github.com/tednaleid/git-tower-beyond-compare-shim

Based on my original gist for PhpStorm + Tower.app diff integration: https://gist.github.com/sc0ttkclark/213fe88f9eacbd5ae58a

Also used the forked gist: https://gist.github.com/dsandor/19bfa4afbfc43cb3aff6f62167a41485

The difference with this one from the fork from @dsandor is that this one is updated with the latest changes from the original gist.
