WebStorm.app (Toolbox) Mac integration with Tower.app for diff and merge

How to use this

1. Add CompareTools.plist and webstorm-toolbox.sh files in the ~/Library/Application Support/com.fournova.Tower3/CompareTools/ directory. You may need to mkdir ~/Library/Application\ Support/com.fournova.Tower3/CompareTools if the folder does not already exist
2. Update the webstorm-toolbox.sh to use your username for the /Users/yourusername/ path and the correct version number (WebStorm > About > Build #WS-XXX.XXXXX.XX where XXX.XXXXX.XX is the version number to use).
3. Run chmod +x ~/Library/Application\ Support/com.fournova.Tower3/CompareTools/webstorm-toolbox.sh
4. Go into Tower.app Preference > Git Config > Select "WebStorm (Toolbox)" for "Diff tool" and "Compare tool", you can optionally enable "Perform directory diff"

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

If I had more time, I would make this handle more dynamically like https://github.com/vdmorozov/mac-jetbrains-sudo-launcher/blob/master/mac-jb-sudo.applescript does. Unfortunately right now it requires you specify the username and version number manually due to how Toolbox installs the app.
