Add some convenient features of Visual Source Safe to Git

• Display the edited files you haven't checked in yet.
• Display everyone else's edited files they haven't checked in yet.
• Show if there's a conflict between a file you're editing and a file someone else is editing.
• Optionally make all the files other people are editing read only on your computer.
• Although there's a user interface you can look at, it's designed so you set it up and forget it's there.
• If you try to save a file and it's read only, Visual Studio will tell you it's read only. Then you know there's a conflict.
• Avoid Git Hell by knowing if there's a conflict before you run git commit.
• Written in Visual Studio 2017. Open source code freely available.
