Detailed Description

All disaster/easter egg vehicles are handled here.

The general flow of control for the disaster vehicles is as follows:

1. Initialize the disaster in a disaster specific way (eg start position, possible target, etc.) Disaster_XXX_Init() function
2. Add a subtype to a disaster, which is an index into the function array that handles the vehicle's ticks.
3. Run the disaster vehicles each tick until their target has been reached, this happens in the DisasterTick_XXX() functions. In here, a vehicle's state is kept by v->state variable. Each achieved sub-target will increase this value, and the last one will remove the disaster itself.
