WINDOWS-BUILD: Fix buildall to work on platforms which have multiple versions of Visual Studio installed

- Added checks for dependencies before execution
- Added setup and update support for local Win32-Development-Binaries repo init
- Added support for operation under both a CMD.EXE invoked from either a git bash process or a natural windows CMD.EXE
- Fixed proper operation for first build operation after the local build repo has been cloned
- Make sure the build is of the latest code in the master branch from the origin repository
