Adds integration of Buck2's C++ targets into Visual Studio. It integrates into the "Open Folder" mode, meaning you need to click "File" > "Open" > "Folder..." and then open the folder with the .buckconfig.

This is still a beta version

Known issues

• Right-clicking a BUCK file to build all targets in it does not work
• Build all does not work
• I haven't tested in repositories with non-alphanumerical folder or target names
• The tests are always compiled in the default target platform
