/*
WARNING: THIS IS STILL EXPERIMENTAL STUFF
I want to have the ability to assign specific behaviors to each room without messing with the main engine
So I'm creating a module for server-side modifications (mods). There is one also for the client.
Their naming convention is roomIdFunction.
The functions are called by the engine at crucial points, only if they exist.
