Copy Windows Spotlight Lockscreens Images

// This script requires ScriptCS (https://github.com/scriptcs/scriptcs) but you can modify it and build it as a C# App
// You run this from inside the target folder (where images are copied to), or pass the target path as a script parameter
// You can also have an "_exceptions.txt" file with images to exclude, so they wont be copied again
