World-Entities hierarchy

[landauf]

We need a well elaborated class hierarchy for the world entities. We need interfaces, abstrac classes, common functions and a totaly new handling of players (can be controlled by human input, AI or scripts) and many other classes. You'll have to rework and norm functions between classes (for example: a player gets damaged; we need the amount of damage, damage type (fire, projectile, toxin, …), origin (think about kill messages in online matches), direction and impulse - or maybe you have better ideas). The basic class too needs several new features (triggers, states, saving/loading functions, …).
