Meteor showers are weak sauce. Make em better.

Honestly, it's so rare that meteor showers happen because the round usually ends before then. I would rather see them occur earlier in the round while keeping them at roughly the same level of destructiveness, I think people will put up more meteor shields if they shuttle isn't leaving anyway in 2 minutes. If it turns out that they cause too much damage to the station on average, we can always scale the amount of meteors based on round time, but I feel like right now it doesn't even matter what we do to meteor showers, because the shuttle basically always leaves before they happen (or at least very close to it).
