Added Windows batch files for automated packaging of fused Windows packages.

They require the tar utility, but that's included in the latest versions of Windows 10. The utility is available for installation on other versions of Windows.

I also found out how to get the Discord RPC library to load with all ways of running the game, but that required changing libs/discordRPC.lua. Binary libraries can only be loaded from the filesystem, outside of a .love archive or fused executable.
