P0-A8: Part 840: Debugging

I have spent some time testing the multiplayer functionality on multiple computers. There were some minor network issues, but these seem to have been fixed, and there doesn’t seem to be any issues with the multiplayer components (despite UNET being deprecated in Unity).

I intend to look into multiplayer testing a lot more in the next few weeks, and add some criticial functionality, such as a character selector, and the ability to create an account, choose a username, etc.
