GotoUdon - 1.2.0 Optional simulator and less clutter in GUI

Note: Sorry for less updates recently, less time + working a bit on other things, including testing some ways to maybe offer networking "simulation".

• Removed settings like worldId that could just been automated
• Hidden setting you probably will not need to change
• Added option to completely remove simulator - it will not even compile code related to it. Useful for troubleshooting or if you just don't use it and only use client manager.
• Now player names will be randomly generated when adding new ones.
• Added ability to select player network id for more advanced testing

Also thanks for growing Japanese community, it's really motivating to see more of you using my tool. I wish I could communicate with you all better.
また、私のツールを日本のコミュニティを成長させてくれて感謝したいです！日本の皆さんともっと仲良くなりたいので、これからもよろしくお願いします！
