Made the server work with the adventure model

* The model was imported from the wrong version, so that needs to be fixed.
* The client side doesn't work at all right now. Use netcat for testing.
* There are inconveniences and bugs in the model (eg. it lists the player among entities)
* Players can just see each other, not interact in any way
But it's a good base.
