When a meteor event triggers it now selects a main edge to arrive from, with a 20% probability to come from either neighboring edge. Will never arrive from the opposite edge.
The meteor event end time is now made more useful, and is based on a longest delay between meteor waves scenario.
The meteor event now supports multiple station Z-levels.
Removes the meteor sounds, as they can rarely be heard over the explosions anyway.
