* Begins work on Planetary meteors
* Work, clean meteor code.
* Continues work. Meteors now handle their own movement and launching.
* New meteor types, some added to waves. Large meteor type fully implemented.
* Fix and adjust for comments.
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.
Merges the two meteor events into one, and now takes severity into consideration instead.
Including the basic meteors there are also new types ranging from flaming to radioactive which may drop appropriate types of ore.
Only two more this time:
Random space dust attack.
Random gravity failure.
Moves space vines from moderate to major events, due to its now more dangerous nature.
Removes now irrelevant alien/ninja customized event handlers.
Adds Excel sheet for aiding in event probability calculations.
