Player move

Move Player over to the accounts app and make it the default user (inherit User instead of just having a one to one relation with it)

This means we no longer need to do any "user.player" / "player.user" things and should be able to customize user(player) much easier

Changing the auth model requires it to be in the very first migration so I squashed all the migrations and did some nasty things so it doesn't look horible - this means you will need to remake the whole db (just docker-compose down and then migrate) but considering noone even used the project yet, this should be much better than having some kind of a complex migration (tbh from what I read I'm not sure this is even possible) that would do the change without losing the database users.
