Visual Studio Code fix

I have been a heavy user of sensible side buttons for a while. I use Visual Studio Code paired with Xcode every day. They are usually side by side on different monitors.

Unfortunately I am in a dilemma. If I enable SSB, my side buttons work on Xcode but not VSCode. If I disable SSB, my side buttons work on VSCode but not Xcode.

This is the fix for that immensely annoying issue.

Additional Notes:

• Removed some warnings
• Reformatted Code with 2 spaces (sorry it looks better :), also not in all places.)
• added .gitignore
• bumped version to 6
• .pbxproj updated with xcode 11 settings
