v3.2.2.0

- Large code refactoring and optimizations
- The more essential SteamCMD directories (config and userdata) will no longer be cleaned up by the program, hopefully to speed up the first call
- Games can now also use SteamCMD as a fallback similar to DLC (previously both steam store AND steamCMD output was required for games, now it's either OR)
