WinUtil.dll recompiled for Win32. Added -SNAPSHOT to versions.

WinUtil.dll recompiled for Win32 because the version in repo didn't work since a package was renamed and WinUtil.dll wasn't recompiled. For now I just created a Visual Studio project. I have recompiled and tested only Win32 version, Win64 version is still untouched.

Added -SNAPSHOT to all artifact versions. Without this Maven won't redownload recent JARs for developers using Sikuli JARs from Maven repo.
