Win32: Add some MSBuild scripts.
Add bin-release to the gitignore file. Fixes an issue with TortoiseGit on Windows relating to that directory.
More specifically: It doesn't like bin-release\lang\.git, but it doesn't need to concern itself with bin-release\* at all.
Merge pull request #5986 from thedax/win32BuildScript
