Handles hooks.
Hooks have a major issue, they are sort of like a poor man's threading. This means get all the issues related to threading. The main issues here are the fact that the hooks can mess with the game state during the update and break everything. The solution is to handle hooks either before the update stage (input stage) or after update stage (render stage). This leaves the update stage as sort of an atomic block that doesn't have to worry about state corruption.
The flaw in this design is that it's still possible for hooks to bash other hooks. Notably the player.teleport() is a very dangerous function as it'll destroy the entire current Naev state which will most likely cause all the other hooks to fail.
Therefore we must tread carefully. Hooks are serious business.
