Player Lists

[gamemann]

This issue is to track progress on implementing player lists for game servers.

Player lists will be a priority after initial release. Initially, I was going to store the player lists inside of a column in the Server Prisma model via JSON. However, due to the amount of players/users we'll have, I believe it'd be better storing them in their own Prisma model so that it utilizes indexing, foreign keys, and more which will result in better performance and scaling.
