The Visual Studio project files can now be created automatically from the GCC
files using the create_project tool inside the /devtools/create_project folder.

To create the default project files, build create_project.exe, copy it inside
this folder and run the create_msvc15.bat file for a default build. You can run
create_project.exe with no parameters to check the possible command-line options.
